How to Optimize Your VoIP Network?

Phone calls continue to be customers’ preferred communication channel for support and service because it is the fastest and most effective. However, if your phone system is not set up properly, you can run into issues that inhibit your ability to provide uninterrupted, reliable customer service.

In this post, we’ll go over the different ways to optimize your VoIP network so you can get started today!

Improve VoIP Connectivity

Setting up your VoIP system means preparing your network and IT infrastructure to support your provider’s service. While the below tips are recommended to implement as you set up, you can also use them to troubleshoot VoIP issues. You can improve connectivity and optimize your VoIP network in the following ways:

  1. Adhere to VoIP Network Requirements
  2. Contact Your VoIP Provider
  3. Run VoIP Connectivity and Speed Tests
  4. Identify VoIP Issues
  5. Increase Bandwidth
  6. Invest in Quality Hardware
  7. Consider Creating a VLAN

When to Optimize Your Phone Network

When your VoIP network isn’t well-optimized, it can lead to reliability and quality issues. And as a business communicating with clients, these issues can interrupt business continuity and make your business appear less reliable and trustworthy.

Common VoIP call quality issues include:

  • Latency
  • Jitter
  • Packet loss
  • Dropped calls
  • Inability to make calls from a device
  • Echoes
  • Broken or muffled audio
  • No audio or one-way audio
  • Phone not ringing on incoming calls, and so on.

And often, these issues originate from your internet and network setup. This is why it’s important to understand what network requirements your VoIP service needs.

For specific fixes for these problems, check out our VoIP troubleshooting guide.

Steps to Optimize Your VoIP Network

Now, when it comes to improving and optimizing your VoIP network, you have multiple options. The key is to identify the problem and then find the best solution. In some cases, your VoIP provider can help. And in other cases, you’ll need to rectify the problem yourself.

So, really, you can start by contacting your provider or running tests on your own. Let’s go over how you can optimize your VoIP network and different factors to keep in mind:

1. Adhere to VoIP Network Requirements

To properly set up a VoIP phone system, you must pay attention to network requirements that enable VoIP to function effectively. This includes:

A good way to optimize your VoIP network is to ensure you’ve done the above-mentioned best practices. These will create a healthy environment for your VoIP phone system.

We’ll talk about some of these in more detail below. Additionally, we put together a comprehensive guide to VoIP network requirements to help you get started.

2. Contact Your VoIP Provider

For a quick resolution — especially if you don’t have in-house network or voice engineers — it may help to first contact your provider. Since they know the network requirements needed to run VoIP properly, they can let you know how your current setup is failing.

They can also provide additional testing and monitoring services to identify the problem and offer solutions accordingly. They should already be monitoring your service, so it is easier for them to determine what is causing the issue.

If you want to exhaust all your self-service options before calling your provider, try the suggestions listed below.

3. Run VoIP Connectivity and Speed Tests

To remedy potential issues and optimize your VoIP network, you first need to know what’s wrong. The quickest way to determine a problem is by running speed and internet connectivity tests on your network. VoIP tests measure the speed, jitter, and latency of your internet connection. Similarly, you can even use a ping test to assess where exactly is the delay or issue occurring within your network or phone system.

Now, some VoIP providers offer their own tools that you can use. But others will direct you to different tools that they trust. Check with your provider about what they recommend or look online for internet, ping, and VoIP tests.

4. Identify VoIP Issues

After you run these tests, you’ll get scores for latency, jitter, packet loss, upload speed, and download speed. This will give you a clear idea of how your network is performing. If any of these scores are outside the acceptable range, you will experience issues with call quality.

Another way to identify VoIP issues is by manually monitoring call quality for jitter, delays, audio issues, etc. You can use MOS scores to get user opinions of a call’s quality – something like this:

MOS Quality Issue
5 Excellent Perfect quality
4 Good Less perfect; may include some loss of quality
3 Fair Slightly strained quality
2 Poor Strained quality
1 Bad Heavily strained quality

Then, you can go back and investigate each call using call detail records, activity reports, and alerts. And you can make this process more effective using a call recording feature, as you can actually listen to the calls with low MOS scores to identify the issue.

Once you determine if the issue is latency, jitter, delays, audio problems, etc., you can fix it. Our VoIP troubleshooting guide (linked above) has different solutions you can implement to resolve these issues.

5. Increase Bandwidth

For voice services and VoIP calls, you need at least 85-100 kbps per call. This number increases when you have additional, concurrent calls. And all of this does not factor in other internet usage and traffic, such as streaming, checking emails, running chat, etc.

Refer to the below table to calculate how much bandwidth you will need for concurrent voice calls:

Number of Concurrent Calls Bandwidth Recommended
1 100 Kbps
5 500 Kbps
10 1 Mbps
15 1.5 Mbps
20 20 Mbps

So, if your business does not have adequate bandwidth, your VoIP network won’t be optimized, and you’ll experience network congestion. As a rule of thumb, try using only 80% of your available bandwidth for all internet-related activities, VoIP calling included. And when you begin to exceed that limit, upgrade your bandwidth.

6. Invest in Quality Hardware

Another way to upgrade your VoIP network is by updating your hardware and equipment. Outdated, legacy equipment may have limited functionality and can degrade over time. Plus, newer software and technologies work better with newer hardware. Consider making the following upgrades if you don’t already have them:

Cabling — Use Cat 5e, Cat 6, or Cat 7 Ethernet cables.

Power — Use a Power over Ethernet (PoE) switch for efficient delivery of data and power to over one wired connection

Infrastructure — Switch to wired connections if currently using WiFi.

Routers — With features like

  • Dual and Tri-Band Frequency — Transmit traffic at 2-3 frequencies, so you can separate VoIP traffic from others.
  • MU-MIMO — Multi-user, multi-input, multi-output that enables each device to have its own data stream connected to the router.
  • WiFi 5 (802.11ac) or WiFi 6 — Higher the wireless, the better.
  • VoIP QoS — Prioritize voice traffic over other traffic.

IP devices — Deskphones, computers, and laptops built to support web calling.

7. Consider Creating a VLAN

Finally, consider adding a VLAN or virtual LAN on top of your existing internal local network. Then, you can put VoIP devices on the VLAN and all other traffic on the LAN. And you can configure the VLAN to give the highest broadcast priority to voice packet transmission by applying QoS settings via VLAN tagging.

VLAN tagging tells which packet belongs to the VLAN specifically and can help separate voice traffic from other traffic passing through your network. Your internal IT team can help you set this up within your infrastructure. However, you can also work with your ISP for professional help.

Optimizing VoIP for Business Communication

VoIP phone systems go a long way to ensure your business can communicate with customers reliably. And this is why many B2B enterprises choose to add IP telephony to their communication stack. But that includes setting it up properly and checking every now and then for potential issues.

Guide to VoIP Network Requirements

Choosing the right provider is not the only factor needed to build a successful VoIP phone system for business communication. You also need to ensure that your IT infrastructure can support the service and your calling needs.

For instance, do you have enough bandwidth to run 50 calls at the same time? Or, are you paying attention to the different types of traffic flowing through your network and the prioritization of voice calls?

If you’re not doing these things, you will run into call quality and reliability issues, which render VoIP relatively weak.

In this guide, we’ll go over key VoIP network requirements and what you need to make your VoIP phone system work efficiently for your business.

We’ll specifically look at:

What Do You Need to Make VoIP Work?

A VoIP service can help your business save on communications costs; 90% on international calling and 75% on operational costs. And since teams can make and receive calls from any location, you can connect distributed teams and increase collaboration and productivity. But this only works if implemented well.

So, besides getting IP phones and a VoIP phone service, what else do you need to make and place web calls efficiently? Voice over IP – as the name suggests – is an internet-based calling technology. So, it depends largely on your internet network to be reliable and high quality. If your network is weak or lacks support, then your voice calls will suffer.

To properly understand the reasoning behind VoIP network requirements, we first need to understand how a VoIP network works. Let’s take a look.

Understanding How a VoIP Network Works

Your business’ internal network (LAN) connects your VoIP devices to your provider. This LAN is typically built on an ethernet infrastructure, especially in commercial and office environments. Your local VoIP network will function over this ethernet setup.

In rare cases where you don’t have an existing ethernet network, it is pretty easy to set one up. Your ISP can help you with this.

Now, when you make and receive voice calls through your VoIP phone number, voice signals are converted into data packets and transmitted across these networks. As the call leaves your internal VoIP network, it will continue to travel over your carrier’s network to its end destination. Upon arrival, the digital packets will reassemble into audio signals.

Understanding how a VoIP network works.

To ensure your VoIP service works efficiently, you must do two critical things:

  • Set up VoIP correctly, meeting its network requirements
  • Choosing a reliable and high-quality VoIP provider.

VoIP Network Requirements

So, what do you need for VoIP to function properly?

  1. Adequate network bandwidth
  2. Wired connections
  3. QoS and data prioritization
  4. Network monitoring and testing
  5. Right equipment
  6. Network security and encryption

Let’s look at each of these in detail!

1. Network Bandwidth

The most important network requirement for VoIP is a high-speed broadband connection.

While IP calling doesn’t need much, VoIP requires adequate bandwidth to handle your business’s specific call traffic. Specifically, you need enough bandwidth to support calls occurring simultaneously.

The general requirement and recommendation for good VoIP call quality is 100 kbps per line for voice services.

Furthermore, it is a good idea to use only up to 80% of the available bandwidth. This means you can use the other 20% for other applications such as email, CRM, streaming, etc. Going beyond that will lead to network congestion and call quality issues. And if you find usage nearing 80% often, it’s time to upgrade.

You can use the below table to calculate how much bandwidth you will need for only voice calls:

Number of Concurrent Calls Bandwidth Recommended
1 100 Kbps
5 500 Kbps
10 1 Mbps
15 1.5 Mbps
20 20 Mbps

2. Wired vs Wireless (WiFi)

Next, when adding VoIP to your network infrastructure, connect IP devices to a wired Ethernet cable instead of WiFi. We recommend using a Cat 5e or Cat 6 Ethernet cable for best results. More specifically, use a Power over Ethernet or PoE switch for efficient delivery of data and power to VoIP devices over one wired connection.

While VoIP can function over wireless networks, it is less reliable. So, another way to prevent congested networks and low call quality is to avoid running VoIP over wireless connections. If your resources are limited to WiFi, then ensure your business uses a professional and secure WiFi connection with at least 802.11ac or Gigabit WiFi for better quality.

3. QoS and Data Prioritization

It is also a good idea to monitor and prioritize VoIP data compared to other network traffic. You know best when your business will experience high call traffic and bandwidth usage. But sometimes, it may be too late to adjust how traffic is prioritized over your network.

Setting up VoIP QoS – quality of service – beforehand balances out how much bandwidth is needed for different types of traffic. This way, you can assign more bandwidth space for VoIP traffic and less bandwidth for video downloading, streaming, etc.

QoS has helped many users avoid or troubleshoot common VoIP quality issues. And because of that, it is typically considered one of the important VoIP network requirements. In fact, it is often something your provider will suggest implementing.

Check if your router supports QoS. To set up QoS, contact your ISP and VoIP provider. Each provider and service will have its own guide on configuring QoS.

For the most part, you can do this by yourself without the help of an IT team. But if you have an in-house IT team, work with them to understand what is being done and monitor it in the future.

4. Network Monitoring and Testing

Another best practice to include in your VoIP implementation is monitoring your network. Now, most providers will monitor their telephony network to ensure their customers are not dealing with any voice calling issues.

But, on your end, you’ll want to regularly monitor and test your network to ensure everything is working properly. There are many speed tests available online that you can use to test your network speed. More importantly, do this when your users run into problems such as audio delays, connectivity issues, and so on.

5. VoIP Device Requirements

Now onto the devices you need to set up your VoIP phone system. This setup will look different for every business and depends on how your teams are distributed, what devices you prefer using, and how they communicate.

But generally speaking, here’s a list of different equipment needed for VoIP:

  1. Headphones or Deskphones — IP-enabled phones
  2. Softphones — web-based app or browser extension
  3. Computers or Laptops — to use in conjunction with webphones
  4. Headsets with mic and noise-canceling technology

6. Network Security and Encryption

Providers will have their own VoIP security and encryption protocols. However, you will also need to protect your business’ network and data. Ensure devices and software are password-protected. Use hardware and software encryption on all applications and devices. Run regular security checks to test the system and look for vulnerabilities or quality issues.

Check out our VoIP security guide for a checklist of best security practices.

Working with Your VoIP Provider

The best way to ensure you set your VoIP phone system up for success is to work with your provider. First, choose a reliable and responsive provider. This is your main point of contact for VoIP-related questions and issues. Then, work closely with them to implement the right protocols and network requirements for VoIP.

How to Change VoIP Providers?

Is your existing phone service effectively supporting your communication needs? If not, it may be time to change VoIP providers.

This article will discuss when switching to another service is necessary and how to do it. So, let’s jump in.

Why Change VoIP Providers?

It’s important to note that not all VoIP services are created equal. Some vendors offer users advanced features and better pricing, while others deliver 24/7 global customer support and greater reliability.

Since the market is saturated with many different VoIP products, finding the right one that fits all your needs may be challenging for some. So, what happens if you sign up with a provider that falls short? Or, what if your communication needs change and your existing service no longer supports your goals?

In these cases, you must change your VoIP provider to sustain business growth, optimize your phone system, and maintain effective communication. This way, you get out of a low-quality service and improve the functionality of your network.

7 Signs it’s Time to Switch Services

So, how do you know when to change VoIP providers? Here are 7 reasons to switch your phone service ASAP:

  1. High, recurring monthly bills
  2. Poor voice and call quality
  3. Lack of global country coverage and call management features
  4. Unreliable, unresponsive customer and technical support
  5. Issues with network connectivity and reliability that lead to an increase in dropped calls
  6. Long-term contracts or commitments with minimal value
  7. Growing need for a flexible and scalable phone solution with high uptime

These are all major signs that your current vendor is holding your business back. Not only is the service hindering your business’s ability to grow, but it’s also preventing you from accessing the many benefits of VoIP. This means it is time to move to a new service that can offer you more while charging less.

Change your VoIP provider in 5 easy steps.

How to Change VoIP Providers: 5 Simple Steps

You can switch VoIP providers in the following straightforward steps:

1. Evaluate Current Service

Start by analyzing your current service. What does it do well? What do you wish you could change or add? You can determine your pain points and priorities by evaluating your current service. Make sure to write down your service analysis, as it will come in handy for the provider research phase (more below).

2. Identify Your Communication Needs

Next, you must identify gaps in your system and what you need to improve caller experience. This will not only allow you to quickly narrow down your search but also ensure you get the best service based on your specific needs.

Here are some questions to help you determine your needs:

• Overall Budget – How much are you willing to spend on equipment, features, add-ons, monthly/annual plans, etc.?

• Desired Services & Features – What is the primary use of your current VoIP service? What services and features do you consider “must-have” vs “nice-to-have”? Which ones can you live without?

• Current Setup – What does your current setup look like? Does it meet the minimum VoIP requirements (adequate bandwidth, stable connection, etc.)? Do you have broken or damaged equipment? How do you plan on deploying your new service? Will it be hosted in the cloud or on-premise?

• Number Porting vs New Phone Number – Do you want to keep your existing business phone number by porting it to a new vendor? Or, are you planning on selecting a new one when you change VoIP providers? And if you want a new one, will it be a local, toll-free or international phone number?

• Commitment & Activation Times– Are you currently stuck in a long-term contract? If so, when does it end or do you plan to break it? How fast do you need a new service to activate?

• Call Traffic Logistics – How many lines or users do you need? What is your average number of calls? Do you see this number increasing? And how does your call traffic typically behave (does it fluctuate or is it consistent)?

In addition to the list above, it’s also essential to consider your business goals, particularly expansion plans. This way, you know that your new service can support your future growth.

3. Research and Select a VoIP Provider

To successfully change VoIP providers and improve your system in the process, research a variety of available services. And remember to compare their service offerings to the needs and pain points you identified in the first 2 steps of this process.

On top of that, pay attention to:

  • Pricing models and hidden/setup fees
  • Specific VoIP requirements and equipment compatibility
  • Service activation times
  • Available services, features, and add-ons
  • VoIP uptime guarantee, network reliability, and crisis management initiatives
  • Long-term contract requirements
  • Service Level Agreements (SLA)
  • Customer and technical support offerings
  • Telecommunications and industry experience
  • Case studies and customer reviews

Now, this step may take a while to see through, as it involves in-depth research. But, it is crucial because it helps you find a reliable solution that’s right for your business. And if you’re struggling to pick between a few services, book consultations to get an even better idea of how they can help your business.

4. Notify Your Current Provider

If you plan on getting an entirely new service and phone number, talk with your current vendor about your plans to change VoIP providers. This way, you know if they charge any termination fees and you can determine a service end date.

On the other hand, if you plan to port your current number to a new service, notifying your provider helps you avoid delays, understand next steps, and, again, allows you to set up a service end date.

Whatever route you take, it’s extremely important that you maintain your current phone service until the activation or porting process is complete. This ensures that you maintain contact with your customers and business continuity.

5. Installing your New Service

While porting your number may take an extended period of time, getting an entirely new service may be fully operational the same day you sign up.

In most cases, installing VoIP doesn’t require any additional equipment. But, the specific VoIP setup process depends on your provider, existing infrastructure, deployment method, and what equipment you want to use.

For instance: If you plan on using softphones for business communication, simply download your provider’s softphone to an IP-enabled device. Then, connect it to your service using your login information. However, using your existing hardware, such as IP and legacy phones, requires more setup. This is because they need to be physically connected to your router or a gateway.

Once you’ve configured your hardware and software, make sure to add your desired users and set up advanced features such as:

  • Call routing and forwarding destinations
  • IVR and call flows
  • Voicemail
  • Caller ID management
  • Call recording and so on.

What is a STUN Server?

When troubleshooting audio quality issues, you’ll probably hear people suggest using a STUN server.

Here’s a brief look at what STUN servers are, what they do, and how they can help improve the quality of VoIP calls.

STUN Servers and VoIP: What’s the Connection?

Network Address Translation (NAT) works by selecting gateways that sit between two local networks:

  • the internal private IP network of your office or home
  • and the outside network such as the internet.

Systems on the inside network are typically assigned IP addresses that cannot be routed to external networks.

“Externally valid Public IP addresses are assigned to a gateway (router or edge device such as a firewall). That gateway creates outbound traffic from an inside system and makes it appear to be coming from one of the valid external IP addresses. Conversely, it takes incoming traffic aimed at an external IP address and sends it to the correct internal system.

This provides accessibility and routing to and from internal network devices and applications. NAT also helps provide security because each outgoing or incoming request must go through a translation process. This process offers the opportunity to qualify or authenticate incoming streams and match them to the outgoing request.” — Anthony Percivalle, Senior Engineer, United World Telecom.

It’s a useful tool. However, using NAT can sometimes prove problematic for VoIP, especially for a VoIP network that relies on UDP.

And that is where a STUN server comes in. VoIP networks use STUN to communicate between two endpoints located behind NAT gateways. But what is it, and how does it do this? Let’s find out!

What is a STUN Server?

A Session Traversal Utilities for NAT or STUN server is a server-client protocol that allows privately addressed clients within a local network to traverse NAT and set up voice calls to a VoIP provider outside of that local network.

The original full form of STUN is Simple Traversal of User Datagram Protocol (UDP) through Network Address Translators (NAT).

A STUN server can be used in several network implementations by protocols such as SIP and WebRTC. This server enables NAT clients (devices running behind a NAT) to identify:

  • its public address or public IP,
  • the type of NAT it is connected to (static or dynamic), and
  • the port translation done by the NAT (the port other devices outside the network can connect to).

By doing this, it enables high-quality and reliable VoIP calls across private and public networks.

How Does a STUN Request Work?

The STUN server is commonly implemented as a client-server protocol with request (query) and response components and a connection to the third-party server located on an accessible network, typically the internet. These STUN messages travel through UDP packets.

Here’s a quick glimpse into how a STUN request and response works:

A diagram showing how STUN servers work.

  • Step 1: A device sends an initial request – binding STUN request – to discover its ports and IP. It sends this through the gateway to a STUN server located outside the local network, typically the internet. These servers usually listen on port 5060 or 3478.
  • Step 2: The STUN server then sends a success response back to the device with the public IP address and port number of the client.
  • Result: When this device makes a SIP-based VoIP call with the external entity (in this case, the VoIP provider), the provider can send responses back to the public IP and new port, enabling easy communication of data and information between the two endpoints.

This way, a STUN server helps two devices running behind a NAT gateway to establish a UDP connection.

Where to Find Your STUN Server?

Some businesses will have access to their own STUN server. Similarly, most VoIP applications have their own default servers, so you can check with your providers and vendors which one to use. However, you can also access an online public STUN list and pick one that works best for your needs. Instead of using a default server, you can enter your own custom server from such a list.

You can always reach out to your provider to determine the best for you.

When to Use STUN Servers for VoIP?

Currently, most applications don’t require a STUN server to work efficiently. But, it can come in handy for troubleshooting VoIP call issues.

Alain Rodriguez, our Customer Service and Tech Support Manager, explains that “if your devices are sitting behind NAT, your VoIP provider may suggest using a STUN server to remedy any VoIP issues you may experience with connection, jitter, or latency.”

Troubleshooting VoIP Quality Issues

Using a STUN protocol is just one solution to fixing VoIP problems. However, you can take other remedial measures depending on the issue itself.

VoIP Billing Increments: Understanding How Your Calls are Charged

When you sign up for a hosted VoIP provider, you’ll rely on your monthly invoices to understand usage and calling charges. But these invoices can look confusing if you don’t understand how your provider bills their service.

To help you understand your VoIP bills, we’ve put together this article on VoIP billing increments.

How are VoIP Calls Billed?

Your VoIP calls are billed based on your provider. Each provider has a different pricing model and different types of costs.

Generally speaking, you can expect two costs:

  • Monthly VoIP line fee and
  • Costs for usage (charged in increments)

While the monthly fee is usually obvious when signing up, the cost for usage (billing increments) is more challenging to determine. So, it’s a good idea to ask your new provider how exactly they bill for phone calls occurring over a month.

What are Billing Increments?

Billing increments refer to the unit of time used to charge a particular service, specifically to indicate the minimum and incremental measures of time.

VoIP billing increments refer to the unit used to indicate how a VoIP service is charged and what the customer is billed for.

Most VoIP phone calls incur fees based on a minimum and increment charge set by your carrier. Let’s define these terms:

Billing minimum — the minimum amount of time your provider will charge for each call.
Billing increment — the amount of time your provider will charge you after achieving the minimum time.

Here’s an example of VoIP billing increments with a 12/6 rate:

In this case, your billing minimum is 12 seconds and your billing increment is 6 seconds.

So, after the first 12 seconds, your provider will charge you again after every 6 seconds.

Again, every carrier does this differently, so it’s important to understand how your desired provider will charge you.

Different VoIP Billing Increments and Pricing Models

Each VoIP carrier offers a different pricing model. And some even offer multiple models, so you can choose what works best for your particular situation.

Here are some of the billing increments currently present on the market:

  • 6/6 billing increment — minimum billing 6 seconds and subsequent billing 6 seconds — talk for 8 seconds, pay for 12 seconds
  • 12/6 billing increment — minimum billing 12 seconds and subsequent billing 6 seconds — talk for 14 seconds, pay for 18 seconds
  • 30/6 billing increment — minimum billing 30 seconds and subsequent billing 6 seconds — talk for 34 seconds, pay for 36 seconds
  • 60/60 billing increment — minimum billing 60 seconds and subsequent billing 60 seconds — talk for 62 seconds, pay for 120 seconds

What is DTMF? How Does Dual-Tone Multi-Frequency Work?

In this post, we explain what dual-tone multi-frequency, or DTMF, is and how it is central to voice calling. This is a telecommunications technology that works under or inside your phone system. So, it is not an extra feature but should come with your phone service.

What is Dual-Tone Multi-Frequency?

Dual-tone multi-frequency (DTMF) produces touch tone sounds heard when pressing a number on a phone’s keypad.

When you press a number key, DTMF sends the following:

  1. signal to your phone company indicating that you want to make a call and
  2. command to the switch.

And it does this by sending two tones – a high- and low-frequency tone – for every number key pressed.

You can learn more about the history and evolution of DTMF here.

How Does DTMF Work?

The dual-tone multi-frequency technology assigns 8 different audio frequencies to the rows and columns of a keypad. The columns have high-frequency signals, and the rows have low-frequency signals. Here’s what that looks something like this:

DTMF frequencies chart

When a user presses a key (number or symbol), a tone generates by combining the high and low frequency of the number. For example, when you press the number ‘7,’ frequencies 852 Hz and 1209 Hz are combined.

The DTMF technology then sends this combined signal over phone wires to the local phone exchange. Once there, the exchange decodes the signals to determine the entire number the user wants to call. Once identified, the call automatically routes to the desired number and destination.

An example of how DTMF tones work.

What is DTMF Used for? Common Use Cases

Besides ensuring that your dialed numbers actually place calls, DTMF technology has revolutionized the way users interact with an outgoing call. For this reason, this technology has many benefits for businesses and contact centers with high call volumes. Let’s look at some use cases:

Navigational Tool

The most common use case for dual-tone multi-frequency technology is its influence on interactive voice response systems (IVR). IVR is an automated call handling system that answers incoming calls, interacts with callers, and directs them to their destination.

DTMF tones are the dominant signaling protocol for interacting with an IVR. An IVR typically provides users with menu options such as Press 1 for Sales, Press 2 for Billing, etc. With DTMF technology, callers simply press a number key to be routed to the desired department.

Information Entering Tool

Another way to use DTMF tones is to let callers input (or dial in) numbers to verify their identity.

For example, they could input their account number, the last 4 digits of their card, their order number, and so on. Then, the auto-attendant or agent can use this information to help them faster.

In some cases, the IVR can collect information before the agent joins the call. In other instances, the auto-attendant may just provide the caller with the necessary response. Such as the familiar: You have a pending balance of $XX; would you like to pay now?

Self-Service Options

Finally, you can also use dual-tone multi-frequency technology to let calls complete certain actions, like:

  • Changing language preferences
  • Make or confirm bookings or reservations
  • Checking bank or bill balances
  • Filling out phone surveys, etc.

Using DTMF Tones with United World Telecom

United World Telecom provides DTMF with our Advanced IVR feature for both IVR menu and input options.

As you build out your phone system within our IVR editor, you can assign departments and agents to different numbers. Callers can then press those numbers on the keypad or enter specific extensions and codes to reach their desired department.

How to Set Up a VoIP Phone System

Upgrading your business communication system doesn’t have to be time-consuming or full of roadblocks.

In fact, VoIP makes migrating to a modern phone system seamless – especially with the right provider.

In this article, we will discuss how to set up VoIP by breaking down both the preparation and implementation processes.

Why Should Your Business Set Up a VoIP Phone System?

Voice over Internet Protocol (VoIP) allows your business to make and receive phone calls using an internet connection and packet switching technology. This tech replaces the physical lines of a traditional phone system with digital pathways – making VoIP more efficient than PSTN and landlines.

Benefits of Using VoIP for Business Communication

Other benefits of installing VoIP include:

• Reduced Overhead Costs – Save on international and long-distance calling fees as well as the cost of routine maintenance and equipment upgrades.

• Ability to Scale – Make changes to your system (such as adding or removing users) as you see fit without applying major changes to your network.

• Increased Mobility and Flexibility – Enjoy access from any location or IP-enabled device. This means you can place and receive business calls from smartphones, tablets, computers, and more. And, you can use Voice over IP to connect your widespread and remote teams.

• Access to Advanced Features – Use advanced communication features like call recording, IVR, and routing. These allow you to customize and build a better phone system that increases caller experience.

• Improved Reliability – Access failover functionalities and ensure your system’s reliability – even during power outages or severe weather conditions. Failover options typically come with a VoIP service.

• Manage Communication in One Place – Manage and access your core communication channels like voice, video, text, and more through one centralized platform. You no longer need multiple services to manage your business’ communications.

Getting Started with VoIP

Whether setting up VoIP within a small business or enterprise, you’ll need a few components to get started. It’s worth noting that your setup may look different depending on your existing infrastructure. But to properly power this technology at its most basic level, you’ll need:

  • A strong internet connection and adequate bandwidth (equipment needed: a modem, router, Ethernet cables to connect everything, and an Internet Service Provider (ISP))
  • IP-enabled devices such as desktops, tablets, smartphones, and IP phones
  • Or media gateways to connect legacy phone systems
  • A reliable VoIP provider (more on this later).

Preparing to Set Up VoIP

Before configuring VoIP, you must define your communication needs, assess your existing system, and do your research. While these steps are not mandatory, it helps streamline your transition. Let’s break these steps down further.

Determine Communication Needs

It’s important to start preparing for your VoIP installation by determining your needs. This information should guide you through the decision-making and transition process – ensuring you stay on track to the best solution. And it will make the selection process more efficient since you’ll know exactly what to look for.

So, how do you define your business communication needs? Start by asking yourself:

  1. What are you planning to use VoIP for exactly? Inbound calling? Outbound calling? Or both?
  2. What is the budget? How much are you willing to spend on equipment, a provider, features, and other add-ons?
  3. What features are “must-haves” for your business and teams? And which ones could you live without, but would be nice to have?
  4. Do you have an existing communication infrastructure? If so, are you planning on completely replacing it? Or do you want to modernize your legacy phones by upgrading them with VoIP? And based on these answers, how do you plan on deploying VoIP? (more on this later)
  5. Are you looking to port your existing business phone number, or will you choose a new one? And if you select a new number, will it be a local, toll-free or international phone number?
  6. How many lines or users do you plan on having?
  7. What is your current average number of calls, or how many calls do you expect to receive? And how does call traffic typically behave (does it spike, or is it consistent)?

Defining the full scope of your communication needs helps you find the best service and setup for your business.

Audit Hardware and Satisfy VoIP Requirements

Auditing your hardware means assessing your equipment and IT infrastructure to evaluate its life cycle and current ability to perform its job. These audits help businesses identify outdated or broken equipment, prevent double-purchasing, and determine what equipment still has value. Once you have a good idea of your infrastructure, you can select a VoIP deployment model (see below) and decide if additional hardware purchases are necessary.

During your audit, it’s also worth evaluating your IT infrastructure to ensure it can support the solution you envision. In other words, make sure your system meets the minimum requirements for installing VoIP. This way, you get the best possible call quality and VoIP performance.

Ensure your infrastructure has:

• Adequate Bandwidth for VoIP – Check that you have an adequate amount of bandwidth available to power your devices and services. Your minimum bandwidth speed for one call or SIP channel should generally be 100 kbps.

• Low Latency – VoIP relies on the internet to transmit calls. So, you need a strong and reliable internet connection. Opt for wired Ethernet connections over Wi-Fi, as it increases internet speed, lowers network latency, and offers a more stable connection. And, perform a VoIP speed test to evaluate your network speed and stability.

• Data Prioritization Options – A congested network leads to problems with VoIP errors. Because of this, make sure your router has data prioritization capabilities like Quality of Service (QoS). This capability will allow you to prioritize and optimize your network traffic – ensuring that VoIP calls receive enough bandwidth.

Satisfying these network requirements will set you up for success with most VoIP services, but double-check your selected provider’s specific requirements.

Explore VoIP Deployment Options

Part of the preparation process is research and information gathering. So, let’s review the different options for VoIP deployment. This way, you understand what is available to your business.

• On-premise Solutions

With this deployment model, you install VoIP infrastructure at your business’ physical location. Companies must purchase hardware like servers, switches, and IP phones. And, you’re responsible for routine maintenance, monitoring, and upgrades. As such, you’ll experience higher overhead costs with this setup.

Best For: Large businesses or enterprises, businesses with high communication needs and a large amount of phone lines, companies with infrastructure already in place

• Hosted Solutions

A hosted VoIP solution means your provider installs VoIP equipment and manages the system for you at their locations. So, you receive cloud phone services without the hassle of routine maintenance, system upgrades, or network routing.

Luke Genoyer, Business Development Manager at United World Telecom, says,“It’s much easier to set up VoIP when you’re going through a hosted provider. This is especially true when compared to installing a PRI or POTS system or even wiring together an on-premise PBX.”

Not only does your business save on costs associated with purchasing and maintaining equipment, but you also avoid the hassle of installing complex hardware. And, your business gains greater mobility and flexibility as hosted VoIP solutions are accessible from anywhere.

Best For: Remote and distributed teams, businesses of all sizes, companies looking for affordable communication solutions

• Hybrid Solutions

The hybrid deployment model allows businesses to plug VoIP solutions into their legacy phones via a gateway. So, the VoIP service is hosted while the equipment is on-premise.

Best For: Businesses looking to migrate to VoIP while keeping and upgrading their legacy phones.

How to Set Up a VoIP Phone System

After completing the necessary preparations, it’s time to install your VoIP network. Let’s break it down into 4 steps:

  • Choosing a reliable VoIP provider
  • Setting up hardware and software
  • Configuring your phone system
  • Testing your network

1. Research and Choose a VoIP Provider

It’s crucial to analyze multiple VoIP providers and services before selecting one. This research guarantees that you get the best solution for your business. Compare your communication needs with each provider’s offering.

Specifically, look at:

• Pricing & Hidden Fees – Review each provider’s pricing options and compare them with your budget. Be aware of per-user, per-month pricing models, as these tend to be more expensive than a flat monthly price. And double-check if they have any setup or hidden fees.

• VoIP Requirements – Ask about the provider’s specific VoIP requirements. Can your system support their solution as is? Or will you have to modify your current infrastructure to run the service?

• Activation Times – Consider how long it will take to get your service setup and if it meets your timeframe requirements.

• Available Features – Compare the provider’s range of available features with your list of must-have and nice-to-have features.

• Uptime & Network Reliability – Assess each provider’s network reliability. Start by looking at their uptime guarantee and crisis management initiatives. And take into account how many Points of Presence (PoPs) they have to fall back on in case of service disruptions.

Customer Support – Pay attention to their customer support offerings. Does the provider offer support in your time zone, region, and desired language? And does your account come with a dedicated account manager?

While this step requires quite a bit of research, it’s worth it in the long run as you’ll end up with a trusted provider and solutions that fit your specific needs. Take your time with this step. With the right provider, you can successfully install VoIP and maintain your system with minimal roadblocks.

2. Set Up VoIP Hardware and Software

Once you’ve activated your service, you’re ready to set up your equipment and install the VoIP system. The specific setup of your system depends on your provider, existing infrastructure, how you plan on deploying VoIP, and what equipment you want to use.

If you plan on using softphones to make and receive business calls, the setup process is quick and easy. Simply download your provider’s softphone to your desired IP-enabled device. Then, connect it to your phone service using your login information.

You can also purchase hard phones, also known as IP phones, that connect directly to your VoIP server. While these phones look like regular deskphones, they have Ethernet ports instead of phone jacks. To set this hardware up, connect the IP phone to your router via an Ethernet cable. Then, assign the device to the appropriate user or extension.

For those planning on upgrading legacy phones with VoIP, you’ll need to purchase a gateway. This bridges the gap between the PSTN and digital networks. Start by connecting your legacy phone to the gateway using the phone jack, also known as a register jack-11 (RJ11). Then, connect the gateway to the internet using an Ethernet cable.

For additional equipment like headsets and microphones, simply plug these directly into your computer, phone, or device. Or connect them via Bluetooth if they are wireless.

3. Configure Business Phone System

After setting up your equipment, start adding your users and configure your desired communication features. Which features you choose and how you go about configuring them depends on your business communication needs. But if you defined them earlier, you’ll know exactly which feature you need to configure.

Consider the following:

  • Create call flows and set up an IVR to handle incoming calls and guide callers through your system – ensuring they end up at the appropriate destination.
  • Implement different routing strategies for after-hours calls, holidays, 24/7 global support options, or to match the caller with their preferred time zone and language.
  • Incorporate failover strategies such as failover forwarding to guarantee all calls get answered, even if the first location doesn’t pick up. This is also great for disaster recovery, as it redirects calls to an available destination.
  • Equip call recording on all or a fraction of your calls for training, quality assurance, or liability purposes.
  • Establish ring groups to effectively manage call volumes and reduce wait times for callers.

4. Test Your New VoIP Network

At this point, you’ve fully installed VoIP, and it’s almost ready to use. But before you start making and receiving business calls, test your system and lines for issues.

When testing, pay attention to:

  • Audio quality
  • Latency or delays
  • Dropped calls
  • No audio or one-way audio
  • Connection reliability
  • Network speed
  • And make sure any features you’ve configured operate how you want them to.

Gregory Porras, Senior VoIP Engineer at United World Telecom, explains that VoIP issues can occur for any number of reasons, which is why it’s important to test your system before going live. He suggests testing your system from your internal, external, Wi-Fi, and VPN networks. Greg adds that call quality should be a top priority – so he recommends double-checking your router’s firewall, QoS, and SIP ALG settings. And, open ports on your router to your provider’s recommended settings.

If all else fails, work with your provider to troubleshoot the problem.

Make the Most of Your VoIP Network

While setting up VoIP may seem daunting and complex to some, it is possible to do on your own. Simply follow the steps above and start using your new VoIP phone system.

And with the right provider, you’ll be able to tackle any issues you run into along the way. United World Telecom offers dedicated account managers and 24/7 global support to all users. While some providers charge a “professional services” fee to help with implementation and training for employees, we include it for free with any of our business plans.

What is Hosted VoIP?

Are you looking for a phone system that offers affordability, flexibility, modern capabilities, and so on. Or perhaps you’re planning on modernizing your current communication setup.

Either way, the solution is simple – hosted VoIP.

In this article, we’ll define hosted VoIP, how it works, its benefits, key business features, and use cases.

Understanding Hosted VoIP and How it Works

Before delving into hosted VoIP, you must first understand VoIP on its own. Voice over internet protocol (VoIP) digitally transmits voice calls over an IP network. This allows you to make and receive business calls through the internet.

To accomplish this, it uses packet switching technology, which converts your voice data into digital packets. These packets are then sent to the receiver via the internet. And once they arrive at the destination, the packets reassemble into voice. This process occurs in a matter of seconds and allows callers to communicate seamlessly.

Now, this brings us to hosted VoIP. There are two general ways to deploy VoIP: hosted or on-premise.

With hosted VoIP, a third-party provider “hosts” and manages the infrastructure on their premises. They then supply cloud communication services to your business through a network connection.

This deployment model allows you to access hosted VoIP services from any IP-enabled device or location. Additionally, this setup is far more affordable than on-premise solutions. This is because you don’t have to worry about routine maintenance, monitoring, and upgrades.

With an on-premise model, your business owns and manages all VoIP infrastructure. In other words, the equipment typically resides on-site. While this option offers full control, it is expensive to set up and maintain as it requires plenty of free space, energy, monitoring, and upkeep.

How Can Your Business Benefit from VoIP?

Many companies choose VoIP as their business phone solution because of its many advantages and capabilities. Here’s how your business can benefit from hosted VoIP services:

• Substantial cost-savings – Save on additional equipment and routine maintenance while avoiding costly international and long-distance calling fees.

• Increased flexibility and mobility – Accessible from any location or device, providing more mobility than traditional deskphones.

• Highly scalable – Upgrade or downgrade your service when needed without changing your entire system.

• Enhanced call quality – Experience clearer sound and better call quality, since VoIP calls travel faster than over traditional phone lines.

• Easy configuration – Integrate it within your existing system, as no additional equipment is required.

• Improved functionality – Enhance your business phone system’s functionality with features only accessible through the cloud.

Hosted VoIP Key Features

As mentioned above, many VoIP providers offer users a number of advanced cloud features with their services. This way, you can effectively manage and improve your business’ communication. Let’s take a look at the top hosted VoIP features:

  • Phone numbers (local, international toll-free, etc.)
  • Call recording
  • Caller ID management
  • Advanced IVR
  • Call flow designers
  • Call routing and forwarding
  • Failover capabilities
  • Softphones or mobile apps
  • Voicemail to email
  • Call detail records and analytics
  • Integrations / APIs

4 VoIP Use Cases

With a clear picture of hosted VoIP and its capabilities, let’s discuss how companies can use this technology to grow their business.

1. Expand Globally

IP telephony is not tied to a specific location. So, you can use it to expand globally, enter new markets, and access a broader customer base. The best part? You can do this without opening a physical location or increasing overhead costs. Simply set up cloud phone numbers in your desired countries or markets. Then, forward incoming calls to your business headquarters.

2. Improve Network Reliability

With access to hosted VoIP’s failover strategies, you can build your network’s redundancy by minimizing downtime and preparing for potential outages. So if your system experiences an interruption, calls are automatically rerouted to an alternate, predetermined location.

3. Offer 24/7 Global Support

Cloud communication services are typically fully customizable to your business’ unique needs. This includes predetermining routing rules and features like time-based or location-based routing. You can use them to offer customers 24/7 global support, increasing customer satisfaction and accessibility.

4. Connect Distributed Teams

You can manage hosted VoIP services in one centralized location and from any location or device. This means teams can communicate via smartphones, computers, tablets, and desk phones. These capabilities make it the perfect solution for connecting local and distributed teams.

VoIP versus UCaaS: Understanding the Difference

More and more SMBs are switching to cloud communication solutions and moving away from landline systems. But why?

Companies adopting hybrid and fully remote workforces need communication solutions that stretch across geographic locations.

This opens up the space for more advanced communication technology such as VoIP, UCaaS, CCaaS, CPaaS, and more. So, how do you decide what solution is best for your business?

This article will look specifically at VoIP versus UCaaS, so you can better decide what phone system will improve your team’s productivity.

Building a Business Phone System: VoIP versus UCaaS

As a network professional, you’ve certainly heard about VoIP before. Voice over internet protocol and IP telephony solutions replace traditional PSTN by using the internet to route calls.

On the other hand, unified communications as a service (also known as UCaaS or UC) groups together various communications technologies into one centralized platform.

You’ll notice in the comparison below that both VoIP and UCaaS have very similar benefits. However, the main difference lies in how they are built and how you can use them.

One way to understand the difference between these services is that VoIP makes UCaaS solutions possible.

VoIP, for example, refers to one specific communication technology, whereas UC is an umbrella term for many different types of communication technologies. Therefore, it is not an easy, 1-1 comparison.

VoIP is typically a voice service that handles inbound and outbound calls. UCaaS, in comparison, brings all communication channels (voice, video, messaging, chats, etc.) into one platform and enables them using IP.

Because of this key difference, VoIP is less encompassing than Unified Communications.

Let’s look at these solutions more closely.

A comparison of VoIP versus UCaaS.

What is VoIP and How Does it Work?

VoIP was designed to provide a landline’s functionality along with cloud-based service’s flexibility and capability. This enables phone calls through an internet connection, removing location-related restrictions.

And since VoIP is software-based, you can easily integrate it with other similar cloud communication software and build a wholesome phone system.

What can you do with VoIP?

  • Place and receive calls online
  • Forward calls from a desk phone to a mobile phone
  • Access call recordings and logs
  • Utilize voicemail to email forwarding
  • Access advanced calling features such as IVR, caller ID management, and more
  • Automate call routing based on various rules
  • Easily manage dial-in conference calls.

Benefits of VoIP:

  • More affordable and helps many businesses drastically reduce costs
  • Easier to scale, both locally and globally
  • Supports local, remote, and global teams through one phone system
  • Provides uninterrupted, high voice quality.

What is UCaaS and How Does it Work?

UCaaS solutions go a step further than VoIP by bringing more than voice to your phone system. As mentioned above, it gives you access to multiple communication channels and apps under one cloud-based roof.

This way, your teams can communicate with each other and customers through the channels they prefer.

And by streamlining communication through one platform, your teams can be more productive as everything they need is located in one place.

What can you do with UCaaS?

  • Integrate email, SMS, video conferencing, chat apps, etc., into your phone system
  • Access various communication features and apps
  • Centralize call management from one platform.

Benefits of UCaaS:

  • Cost-efficient and scalable solution
  • Use and manage from anywhere in the world
  • Supportive of global and distributed workforces
  • No hardware or maintenance required.

Which Communication Solution Should I Choose?

As you can see, there are benefits to both VoIP and UCaaS solutions.

However, which solution you need depends on your requirements and resources.

For instance, enterprise-level businesses might find more use in a UC solution that supports their teams and provides more communication and collaboration options. However, if you’re an SMB that needs only voice support across local and remote teams, then a VoIP solution will meet your needs.

One important thing to note is that both solutions will allow you to centralize and scale your solutions as needed. VoIP lets you consolidate different local, regional, and global voice carriers under one carrier (i.e. your VoIP provider). And UCaaS lets you consolidate different communication channels and apps under one service provider.

In fact, you can even add a VoIP service to your UC stack for voice support. By consolidating, you reduce your overall total cost of ownership (TCO) across different channels or providers.

So, whether you start with VoIP or UCaaS, you can grow your communication stack at your own pace via integrations and APIs. The real question is — what do you need right now, and what can support your plans for the future?
