Voice over IP is the new standard when it comes to business telephony.

In VoIP, voice is converted into data packets and sent over the internet using communications protocols. Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are both commonly used protocols for data transfer over the internet.

But how do you decide which is better for your business VoIP system? Here we compare TCP versus UDP, so you understand how these protocols affect VoIP calls.

Is TCP or UDP Ideal for VoIP?

The short answer is that UDP provides a better experience for VoIP users. Using UDP will help minimize network jitter and latency to ensure strong connections for your business phone calls.

Why Do TCP and UDP matter for VoIP?

Well, VoIP sends data packets over the internet.

These data packets consist of a header, which includes information about where the packet comes from and where it should go. They also have a payload, which is the actual data being transported by the packet.

TCP and UDP are just two different types of data packets. Both carry a payload and use internet protocols, but each works slightly differently.

Why is UDP Better Than TCP for VoIP?

Well, VoIP traffic is fast-flowing. A typical data packet contains 10 to 30 milliseconds of audio. Essentially, many, many data packets are sent one after the other. If a few packets are lost here and there, your conversation will probably remain unaffected.

Here’s an example:

Picture a well-trafficked highway; if one of the cars on the highway breaks down, you wouldn’t stop the flow of traffic just to wait for that one car. It’s better to just maintain the flow of traffic.

In the case of VoIP, TCP tries to recover lost packets, causing retransmission delays which stop the flow of voice traffic. UDP lets voice traffic continue to flow.

If you wait for and try to recover lost packets, the quality of your VoIP calls is going to be very low.

Let’s look at TCP and UDP in more detail.

UDP – User Datagram Protocol

This protocol is one of the core members of the IP suite.

UDP is generally better for real-time and high-performance applications like VoIP, which can’t afford retransmission delays. With UDP, there are no retransmission delays.

Here are some of the factors that make UDP ideal for VoIP:

• Connectionless — Avoids the overhead associated with establishing a 3-way handshake.
• No retransmission delays — If packets are lost, TCP will try to retransmit and recover lost packets, causing delays. This is not the case with UDP.
• Speed — UDP is faster, simpler, and more efficient than TCP.

However, UDP also has some downsides compared to TCP:

• No guaranteed ordering of packets — VoIP audio might be transmitted in a slightly different order than how it was sent.
• No protection against duplicate packets.

In some cases, these disadvantages can lead to jumbled audio.

However, UDP is still always recommended for VoIP calls.

TCP – Transmission Control Protocol

This protocol is one of the most commonly used protocols within the IP suite because it ensures the integrity of end-to-end data delivery over a network.

Here is a quick overview of the Transmission Control Protocol:

• Connection-oriented
• Good failure recovery
• High error rate handling and error-checking
• Sequencing – packets arrive in order at the receiver
• Relatively slower than UDP.

TCP is connection-oriented, which means that a connection must be established before data transmission takes place. The connection must also be closed after transmitting the voice packets. This comes with high overhead.

It also provides extensive error-checking mechanisms. If packets are lost, TCP will try to recover and retransmit those packets.

Your VoIP lines will become garbled due to packets trying to recover themselves, making it difficult to make sense of conversations.

TCP is ideal for applications like peer-to-peer file transfer, secure shell, and Internet Message Access Protocol (IMAP), for example. But, it’s actually harmful to low-latency connections like VoIP.

TCP versus UDP: What Do VoIP Experts Recommend?

As a network administrator or VoIP engineer, you’ll want to remember that UDP is ideal for VoIP and SIP connections.

Using UDP will help improve call quality significantly. It will also help with device registration. If you’re trying to register lots of VoIP devices on your network, TCP will slow down your servers.

Voice over IP or VoIP has been a vital business communications tool for many years.

While the technology is still developing, a large percentage of organizations around the world have already adopted it. VoIP has many benefits, including cost savings, scalability, and global accessibility.

However, some countries have banned VoIP, including the UAE and other Middle Eastern countries. Why? Let’s take a look.

Which Countries Have Banned VoIP?

Currently, there are around 20 countries that regulate or block VoIP calls. Here is a list of those countries, along with more details about VoIP restrictions in each country.

Why is VoIP Banned in Some Countries?

Countries around the world block or restrict VoIP calls for several reasons.

The first reason to block VoIP calling is to preserve government profits. Various state-owned telecom monopolies worldwide — especially in the Middle East — rely on international calling and voice communications as a major source of revenue. Large revenue streams would dry up if these countries allowed VoIP.

Security and privacy are additional reasons for countries blocking VoIP. Some countries claim that their VoIP bans serve to protect society from negative influences that could harm the public interest. Others block the technology for security reasons during times of political turmoil and to prevent cheating.

Reasons VoIP is Blocked in Dubai and Kuwait

UAE is an expat-majority country. Many people in the country want to call their loved ones back home and thus require international calling services. However, the country has two government-owned monopolies – Du and Etisalat. Both operators take measures to ensure VoIP does not endanger their revenues.

Kuwait has a similar situation where local authorities look to preserve their revenues derived from voice communications. If they allowed VoIP in Kuwait, they would lose a significant source of revenue.

How are VoIP Bans Affecting People?

VoIP bans are nothing new. In fact, they started years back in 1999, around the time the technology started becoming popular. The effects of these bans can be significant.

For example, many people living abroad cannot communicate with their families back home. The exorbitant international calling rates imposed by monopolies prevent people from calling their families.

As a result, people are growing more frustrated and sharing those frustrations online.

Looking Forward

Local and regional telecom operators want to preserve their profits. It’s understandable. But residents in many countries have called to end VoIP bans.

So, VoIP laws might change around the world. There have been ongoing negotiations between big tech companies and some of the countries blocking VoIP.

For example, Microsoft and Apple are negotiating with countries to repeal their bans on Skype and FaceTime. If these negotiations go well, perhaps the countries will also start to allow businesses to use VoIP. But for now, the technology remains banned in some countries.

VoIP Alternatives for Blocked Countries

You can use three major alternatives to VoIP in countries where restrictions apply. These three methods — VPN, local access numbers, and international callback — all offer significant cost savings compared to using services from telecom monopolies.

However, governments and ISPs in those countries know of the methods used to bypass their restrictions. While these VoIP alternatives may achieve their purpose, authorities may consider them illegal.

So, even though an alternative may work for a given time, it may soon incur restrictions or legal repercussions.

1. VPN Tunnel

A VPN tunnel is the first VoIP alternative for countries with VoIP restrictions. Users will simply connect to a VPN that encrypts their traffic and hides their IP addresses. They’ll be able to access VoIP software to make and receive calls.

2. Local Access Number

The second major VoIP alternative is using a local access number to dial out. Your service provider would offer you a local or freephone number that you could call, enter a PIN, and dial the number you want to reach.

3. International Callback

Finally, an international callback solution acts as another strong alternative to VoIP in countries with VoIP bans.

Businesses in restricted countries would dial a trigger number, hang up the call, and then receive a callback. Upon receiving the callback, they would enter the destination number to call and connect.

A system outage or any type of downtime can significantly impact your company’s ability to close sales or deliver customer support. This may result in a loss of business continuity and revenue. So, maintaining a cloud phone system with a high VoIP uptime and network redundancy is essential to your business’ ability to function.

Are VoIP Systems Reliable? Why VoIP Uptime is Important

Since a redundant architecture is critical to business operations, how reliable are cloud-based communications?

You may be surprised to hear that VoIP networks are more consistent than the wired setups of the PSTN. Landlines are susceptible to power outages, severe weather disruptions, and phone line damage – causing lengthy downtimes. This is because landlines have a single point of failure, meaning your entire system stops working when it fails.

IP telephony eliminates wired setups. Instead, all you need to get started is a stable internet connection. And even if your internet goes out, you can simply forward calls to another destination. So, cloud-based systems continue working during power outages, inclement weather, and more – making them more reliable than traditional phones.

While hosted solutions are certainly more trustworthy than landlines, it’s still critical to consider a provider’s VoIP uptime. Without a high uptime guarantee from your provider, you’re at risk of serious downtime. And downtime means tough consequences such as losing customers, profits, productivity, and more.

What Exactly is VoIP Uptime?

In other words, it’s a metric used to determine the provider’s quality of service, performance, and reliability. In contrast, “downtime” indicates the time a service spends offline, out of operation, or “down.”

You can usually find uptimes listed on your provider’s website, in their Service Level Agreement (SLA), or by contacting them directly. To determine VoIP uptime, most providers either use a monitoring service or measure it themselves using simple math.

It’s essential to confirm that your provider includes both scheduled (maintenance, upgrades, etc.) and unplanned (disasters, power outages, etc.) downtimes in their assessments. This way, you know their uptime is accurate.

What Does 99.99% Mean?

Many cloud providers use percentages to communicate their VoIP uptime to customers. These percentages typically start at 99% and go up from there. However, providers can’t guarantee true 100% uptime. This is because networks are susceptible to damage from natural disasters, cyberattacks, and other unforeseen technical issues that cause service interruptions.

Now, you’re probably thinking – If I can’t have 100% uptime, 99% is exceptional. However, while 99% is undoubtedly better than 75% uptime, it can still yield substantial downtime for your business.

In fact, every “9” in an uptime guarantee is significant. It lets you know how much downtime to expect during a given year. For example, 99% uptime is equivalent to 3.65 days of downtime per year. Whereas 99.99% (also known as “four nines”) is only 52.60 minutes of annual downtime.

Here’s a table listing the range of VoIP uptime percentages and how much downtime you should expect with each:

How Do Providers Ensure 99.99% VoIP Uptime?

It’s important to understand how providers ensure reliability and guarantee 99.99% availability. This way, you know exactly what to look for when choosing a provider.

• Global Points of Presence (POPs)

Having several global points of presence allows providers to establish a high availability service. If one server fails, providers can redirect traffic or fall back on a different POP. So, you never experience downtime if your provider experiences an outage.

For example, if your provider’s Seattle-based POP failed, they could instantly route call traffic from the Seattle server location to another US-based POP.

• VoIP Security

While VoIP is fairly secure as is, your provider might face security risks like Denial of Service (DOS) that compromise their system and lead to downtime. So, it’s necessary to look for a trustworthy provider that meets the minimum security requirements for your specific communication and industry needs.

Search for providers with voice encryption security like Transport Layer Security (TLS) and Secure Real-Time Transport Protocol (SRTP) and those with regular system security checks and firewalls. Providers with these security practices are more likely to deliver a consistent and secure business phone system with a high VoIP uptime.

• Networks of International Carriers

Selecting a provider that partners with multiple international carriers yields similar benefits, as discussed in the POP section. Working with numerous global carriers allows providers to reroute calls seamlessly to alternate destinations if one carrier fails. So, your provider (and your business) never experience prolonged outages or downtime. This helps providers build a more reliable and redundant service with high availability.

What Uptime Guarantee is Right For Your Business?

The answer to this question depends entirely on your business operations, communication setup, and service demands. 99.999% uptime is the industry gold standard – as it only allows about 5 mins of downtime per year.

But when determining the right uptime for your business, it’s helpful to ask yourself:

• How integral is your cloud phone system to your critical, everyday operations?
• How much downtime can your business afford?

Then, based on your responses, select a provider with your preferred VoIP uptime guarantee.

Best Practices for Developing a System with High VoIP Uptime

While high availability falls mainly on your provider, it’s still up to you to build a redundant system and minimize downtime for your business and customers. Let’s review the best practices for developing a system with high uptime.

1. Carefully select your provider

Selecting a trustworthy provider with the right VoIP uptime for your business is crucial to developing a consistent network. When researching cloud telephony providers, evaluate the following factors:

• • Availability guarantees
  • Redundancy methods (multiple POPs and carriers)
  • VoIP security measures (voice encryption, firewalls, regular security checks)
  • Disaster recovery and business continuity plans.

2. Double-check Service Level Agreements (SLA)

Many providers list their uptimes on their websites, which may not always be accurate. So, it’s important to double-check a provider’s service level agreement. This document will list their true uptime percentage and permitted downtimes. The SLA may also list terms and conditions for what happens if their actual uptime dips below their guarantee.

3. Monitor your system

Regularly monitoring your VoIP system allows you to track any network issues causing interruptions. Simply start by integrating an open-source or paid monitoring service into your existing setup. Then, you’ll be able to quickly identify and troubleshoot your VoIP system.

4. Implement failover strategies

With failover strategies in place, you’ll build your network’s redundancy. Even if your business experiences outages or crises, your system will continue to work with failover methods. Consider the following:

• • Use failover forwarding to route calls to alternate locations if the first destination is unavailable
  • Set up a backup or alternate internet connection
  • Opt for hardware that is simple to repair or includes a warranty
  • Disperse your teams, servers, and other systems across multiple geographical locations
  • Backup all mission-critical data, documents, applications, and so on
  • Create an in-depth disaster recovery plan and use it to train your teams.

Good call quality is essential when communicating with customers and prospects. This is because it’s a first (and rather important) impression of your business and its reliability. 40% of customers stated they stopped doing business with a company due to poor customer service, and this includes a bad caller experience.

Part of customer service is being able to communicate on the phone without any hiccups or interruptions like muffled audio or dropped calls. So, how can you achieve the best VoIP call quality for your business? Let’s take a look!

Improving Call Quality for Your VoIP Phone System

VoIP providers exist in abundance these days. Some are fly-by-night using least-cost routing (LCR) with low-quality termination. Others offer expensive plans with limited global coverage and no redundancy.

Along with low-quality cloud phone service providers, many factors affect good VoIP call quality. Part of improving voice quality over your phone system is correctly identifying the issues and resolving them.

Common VoIP Issues

In order to improve VoIP call quality, you need to be aware of the different issues affecting voice quality. These are the most common voice over IP issues that you’ll need to troubleshoot:

• Inability to make calls from a device
• Dropped calls
• No sound
• Jitter
• Echo or delays
• Broken or muffled audio
• Latency
• Packet loss

It is crucial to identify what VoIP problem your system faces. It helps you take the right course of action to improve your network’s functionality. Finding a high-quality VoIP phone service provider can take care of most of these issues. That aside, there are a few tweaks you can make to your system on your own. Here is a VoIP troubleshooting guide to get you started.

How to Achieve Best VoIP Call Quality?

Take these steps to achieve good VoIP call quality for your cloud phone system:

1. Measure your VoIP call quality
2. Ensure you have the right equipment
3. Troubleshoot VoIP quality issues
4. Disable SIP ALG
5. Troubleshooting with VoIP QoS
6. Switch to a new provider

1. Measure Your VoIP Call Quality

It is vital to constantly monitor and measure VoIP call quality. Mean Opinion Score (MOS) measures VoIP quality by scoring a call from 1 (bad VoIP quality) to 5 (excellent VoIP quality). A good VoIP call quality MOS score falls between 3.5-4.2.

Here’s an example of what a MOS score chart looks like:

Test and measure call quality by monitoring jitter, latency, and packet loss. Additionally, call detail records and activity reports will help you identify where your call quality might be lacking. Then, you can determine how to resolve the issue.

2. Ensure You Have the Right Equipment

Purchase the right equipment to support your call volume and agent requirements. Here is a list of equipment needed for VoIP:

• VoIP (hard phones or softphones)
• Computers or laptops
• VoIP phone service
• Headsets with a microphone and noise-canceling technology
• High-speed and reliable data that meets essential VoIP bandwidth requirements

3. Troubleshoot VoIP Quality Issues

Besides finding the necessary equipment, it is crucial to test your VoIP phone system periodically. Here are some ways to troubleshoot VoIP call quality issues on your own:

1. Check your internet speed
2. Review network and equipment configuration
3. Identify and resolve jitter, latency, and packet loss issues
4. Check cables connecting devices and replace faulty wiring
5. Invest in good headsets
6. Avoid hubs on your local access network (LAN)

If you still suffer from low or bad call quality after trying these troubleshooting methods, then the problem may lie in your VoIP service.

4. Disable SIP ALG

Most internet routers come with the SIP ALG feature activated. SIP ALG — also known as Application Layer Gateway — prevents problems caused by a router’s firewall. It does so by monitoring and modifying VoIP traffic, as needed, to improve connectivity.

However, the downside is that VoIP traffic (voice data packets) can get lost due to router firewalls when transferred between the phone and the VoIP provider. This can lead to:

• One-way audio
• Phone not ringing for incoming calls
• Calls sent to voicemail directly
• Dropped calls

So, if your VoIP issues persist after trying these troubleshooting methods, you may need to check and disable SIP ALG.

Disabling SIP ALG depends on the type of modem you use. For most routers:

• Log into your router’s control panel.
• Navigate to Advanced or Security settings.
• Locate SIP, ALG, or Firewall settings (depends on your router’s set-up).
• Uncheck the SIP or ALG box.
• Save and reboot/restart your router.

If router settings are not clear, reach out to your internet provider for help.

5. Troubleshooting with VoIP QoS

VoIP Quality of Service (QoS) is the process of addressing and fixing voice quality issues. QoS prioritizes network traffic passing through a router. The end goal is to offer users acceptable-to-good service.

Routers handle data (and voice) packets on a ‘first in, first out’ basis. This way, all traffic on every device within your network is considered a priority. When too many people use the internet simultaneously, these packets end up waiting in long queues. This means, your call quality competes with other internet traffic on your network — leading to low voice quality.

QoS balances out bandwidth distribution across different types of traffic and devices. This way, you can prioritize what traffic gets through sooner and hassle-free to achieve the best VoIP call quality.

Set up VoIP QoS by reaching out to your internet supplier, VoIP providers, and IT team. To learn more, check out our guide to VoIP QoS standards and requirements.

6. Switch to a New Provider

Finally, if the above methods don’t work, it might be time to find a new provider to meet your business’ exact needs. Sometimes, no matter how you try to improve your call quality, the problem may lie in the phone system itself. Research different cloud phone service providers to understand how their system and phone network works. Consult with telecom experts to find the right solution for your business communication needs.

Resolving VoIP Call Quality Issues

Achieve the best VoIP call quality for your business by trying these different troubleshooting methods. And if those don’t do the trick, reach out to your VoIP provider.

Has your business considered upgrading its legacy ISDN phone system to gain new features and capabilities? Then, you must consider an ISDN to SIP migration.

SIP trunking is cost-effective and highly scalable. And this makes it an excellent choice when upgrading your phone system.

Here is a brief guide to replacing ISDN with SIP trunking, including the benefits of an ISDN to SIP migration and the different steps involved to make this transition smooth and cost-effective.

Why Switch to SIP?

SIP phone systems are often considered a modern alternative to traditional business phone systems. By replacing ISDN with SIP systems, you can add more flexibility and scalability to your phone system.

It is a good practice to upgrade legacy phone systems to take advantage of updated and advanced technologies. Here we will look at how you can migrate to SIP and what an ISDN to SIP plan looks like.

How Can SIP Trunking Benefit Your Business?

There are many benefits of switching to SIP trunking, from making your phone system cloud-friendly to aiding in global expansion to bringing more flexibility.

SIP trunking uses session initiation protocol (SIP) to send voice, video, text, and other unified data through the internet instead of traditional POTS lines. With this ability, you can run your business communications from any location and connect with your team wherever they are located.

And the best part? You don’t need additional hardware or new equipment to get your SIP system running. Global SIP trunks can easily integrate within your existing PBX. So, you do not need to install a new system. Simply bring SIP trunking into your current system. Additionally, your business can even expand to new markets and regions without increasing overhead costs.

So, with SIP trunking, you get a more advanced and scalable phone system while keeping your communication-related costs low.

What to Keep in Mind When Migrating to SIP Trunking

When doing an ISDN to SIP migration, note that:

• You will need to conduct an audit of your current phone system to gauge the scope of the migration.
• Since SIP can work alongside ISDN, switching won’t cause any downtime or interruptions.
• Tests that ensure the system runs smoothly can be conducted around your business’ schedule and activity.
• Research different SIP trunking providers to get a sense of what they offer and what their rates are.

Debunking SIP Trunking Myths

When it comes to new (and complex) technology, it is easy to get sucked up in misinformation and doubts. And so, before we discuss how to migrate from ISDN to SIP, let’s go over some common SIP trunking myths and discuss them:

• SIP call quality is poor — When it comes to digital communication, there is a tendency to believe that communicating over the internet can cause packet loss, latency, and network jitter. But SIP trunking uses dedicated IP connections designed and optimized for high call quality. Because of this, they offer the same, if not better, call quality than ISDN calls.
• SIP trunking comes with hidden costs — SIP trunking is a cost-effective alternative with two primary costs: monthly fees and call costs. You choose the plan at the beginning of your contract. With the plan, you can make and receive local and international calls for low costs. And there are no installation or set-up fees involved. In fact, with some providers, you won’t even pay a cancellation fee, if you choose to find another provider. One additional fee might be to upgrade your PBX system and internet bandwidth if you have low internet capacity. But even with these costs, you will find the service ROI-friendly.
• SIP trunks are not secure — Another common misconception is that cloud communications (like other internet services) come with cybersecurity risks and can be easily hacked into. However, with advanced technology, cloud communication, and SIP trunking providers offer a great deal of security. Additionally, you will need to work with your internet service provider to ensure firewalls and security measures are in place.
• Migrating to SIP will result in downtime — As we mentioned before, many are afraid that switching services or communication systems can lead to interruption and downtime. However, with SIP trunking and a quality service provider, you can minimize VoIP downtime and migrate without pausing your service.

ISDN to SIP Migration in 7 Steps

So, what does an ISDN to SIP plan entail and how can you prepare for such a migration? Here is a 5-step plan to replace ISDN with SIP trunking:

1. Identify and Document Your Requirements

Before you get started, you need to identify what you need from this migration:

• Do you need new business phone numbers? If so, how many numbers do you need?
• What types of numbers do you need: local or toll-free?
• Do you need call management features such as cloud IVR, auto-attendant, call queues, call monitoring, and so on?
• What locations do you need calls forwarded to?
• Do you need extensions or dedicated numbers (also known as direct inward dialing numbers) for specific employees or departments?
• Do you need a softphone to support remote workers?

It is also a good practice to document what you currently have and want to keep, such as phone numbers, extensions, voicemail inbox, etc.

Once you determine what you need from your new system, you can start planning for the SIP migration.

2. Communicate with Your Employees

Before making the switch, bring your employees into the migration process. Get their input and feedback to identify additional areas of conflict and improvement. Some questions to ask employees include:

• What do you think of our current business phone system?
• Have you encountered any issues using this phone system? If so, provide details.
• What would you like from a new phone system? Explain why.
• Can you think of anything that will improve internal and external communication?

3. Make a Plan and Scope the Job

The next step to replacing ISDN with SIP is to make a plan. This will help you determine what your business should expect in terms of scope, transition, and cost. Depending on the state of your current system, you may have to transition in parts (floor by floor or branch by branch) or migrate the entire system in one go.

Work with your communications or SIP trunking provider to get an idea of what the transition will look like, and how your business can prepare. When preparing your plan, consider the following:

• Employees — List down all staff members and collect their contact information.
• Vendors and suppliers — List down contact information for essential vendors, suppliers, and service providers.
• List all communication equipment — Create an inventory of all business-related phones, laptops, computers, desk phones, fax machines, smartphones, etc.
• Call routing — Identify what numbers will route calls to which numbers and locations and when.
• Backup data — Make sure information and data are backed up and that backup processes are working properly.
• Setup safekeeping for critical data — Keep critical data extra safe as you may need this to enact disaster recovery and business continuity. Think logins and passwords, alternative numbers and phone and lines, etc.
• Include remote working capabilities — Here’s an opportunity to explore remote working options for your employees. Review how your new system can support this flexibility.
• Create and test a business continuity plan — This plan will help your business continue working and offer services if something goes wrong.

4. Conduct an Audit: Evaluate Existing Systems

Next, evaluate your current system and anticipate possible problems and changes required. Look at the infrastructure and bandwidth capacity. What is your current system lacking that a SIP phone system can solve?

Check with your SIP provider how much bandwidth and network capacity you will need for your business’ call volume. This information will help you decide if additional connections are required to prioritize voice traffic over other internet usages. Similarly, communicate your call volume expectations with your provider. They will help you understand what infrastructure will work best for your business needs.

Lastly, you may even want to let your provider on future expansion plans. This will help you determine if this provider’s service is scalable and can assist your business in growing when it is ready.

5. Get and Install a SIP Trunking Service

Once you’ve completed the audit, the next step is to find a reliable SIP trunking provider and subscribe to the service. Research different providers to get a sense of what they offer and how much they charge.

You should also look for additional features and tools they offer that can further enhance your business communication system; for example, call management features like call routing or softphones, and so on. Another important factor in choosing a SIP trunking provider is their support team. Is their support team easily accessible? Do they offer 24/7 customer support, in case your business needs help off-hours?

Once you’ve settled on a SIP provider, it’s time to set up and get your SIP system up and running. One significant benefit of replacing ISDN with SIP is that SIP trunking requires less equipment and hardware. And since most SIP services are hosted and maintained by your SIP provider, you have little to no installation. You might need to tweak and adjust minor things, and you might choose to install the service section by section. This ensures no downtime or interruption.

Finally, prepare for the ISDN to SIP migration by getting the right equipment ready.

6. Test Your New SIP System

As you set up your SIP phone system, you must test it and its different components to ensure everything is working smoothly. Most SIP systems can integrate with other business applications such as CRMs, video conferencing tools, APIs, and so on. Test your system with core business applications to identify any issues or hiccups. Similarly, your provider should test the service and phone numbers before the system goes live. Keep your business continuity plan ready, in case there are any issues and you need a backup.

7. Go Live and Make Business Calls

Finally, once your SIP system has been tested and any issues have been resolved, you can fully switch over to SIP. The installation and activation of the system is relatively quick; it is the preparation that can take some time. However, with the right SIP provider and the right tools, this transition will occur smoothly, and your business communication system will work effortlessly.

To get the most out of your VoIP phone system, you need the right VoIP equipment to support your business communication needs.

While most newcomers consider VoIP to be expensive and complicated, the truth is that the technology is fairly simple and inexpensive. There is not a lot of hardware or expensive technology required.

In fact, with VoIP, you can convert existing technology into business powerhouses. How?

Let’s have a look at the equipment needed for VoIP.

Must-Have VoIP Equipment in 2024

What equipment is needed for your VoIP system needs depends on the type of VoIP user you are—residential user or business user.

A residential user will need only a PC / laptop, softphone, and a headset. A small business, on the other hand, might need more. Business users will need a web phone or softphone, a computer, a headset, high-speed internet or data, and a business VoIP subscription.

Without the right VoIP equipment, you will struggle with poor VoIP call quality, leading to frustration and miscommunication. To combat this proactively, make sure you get the right equipment and VoIP setup.

Here is a checklist of equipment needed for VoIP to use your service successfully:

1. VoIP Phones: Hard Phones or Softphones

The main VoIP equipment you need is a phone to make and receive calls. Many VoIP and virtual phone service providers offer global call forwarding to route calls internationally to specific locations and numbers. This way, you can divert calls to your VoIP phones or locations as needed.

A VoIP phone uses IP technology (the internet) to transmit calls between two or more parties. There are two types of VoIP phones:

• • Hard phones — are like traditional phones but come with specialized digital hardware.
  • Softphones — are web-based applications or software that can be downloaded on different devices.

You can even use a combination of both types of VoIP phones to support in-office and remote users. Since softphones can be used from any location and device, you can

2. Headsets

Next, you will need VoIP headsets for your users. VoIP hard phones come with a microphone and receivers. However, if your users use a softphone, then they will need a headset with a microphone. While the tendency is to purchase inexpensive VoIP headsets, these headsets can lead to VoIP issues such as latency and network jitter.

Take time to find good quality headsets that are hands-free, remain connected, have noise-canceling technology, and, overall, improve call quality.

3. Computers or Laptops

Next, you will need personal computers to complement your service. You can use computers and laptops to not only get work done but also make and receive your VoIP calls through a softphone. This way, users can manage calls and update their CRM or task managers as they work without interruption. And, users working remotely can also use their laptops to connect through cloud-based and virtual software and continue working.

4. High-Speed and Reliable Data

Next, if you’re using VoIP for business, then you need a robust internet setup. This includes a reliable and stable internet connection with a modem and router. VoIP does not demand much but needs enough bandwidth to handle your call volume.

While setting up your internet, work with your internet service provider and IT team to set up VoIP QoS for your VoIP service. VoIP Quality of Service (QoS) can help troubleshoot voice over IP issues. When QoS is set up, you can prioritize network traffic to make business calls a high priority. This way, even with everyone using the internet for multiple reasons, the quality of your business calls remains untouched.

5. VoIP Phone Service

Finally, you will need a VoIP phone service, and you can get this from any virtual phone service provider. However, you want a provider who offers quality service for a reasonable price and has easy-to-access, responsive customer service. When settling on a VoIP provider, ask about the installation and set-up processes and the different features that come included with the service. Look for customer reviews and case studies to get an idea of how the product works in action. Then, choose a provider that meets your needs and budget.

Are you noticing more dropped calls or jumbled audio during your business VoIP calls? While cloud phone services can be much superior to traditional phone services, they cannot guarantee high-quality phone service at all times. This is because many factors influence the quality of a VoIP call. Here we discuss the importance of VoIP QoS and how to set it up.

VoIP QoS: Definition, How it Works, Best Practices

VoIP Quality of Service (QoS) is the process of addressing and fixing voice quality issues so your employees can effectively communicate with business contacts. This process is crucial to understanding how your business phone system works and what you need to do to improve it. QoS is one such way to maintain good call quality.

What is VoIP Quality of Service (QoS)?

VoIP QoS prioritizes network traffic passing through a router to provide acceptable-to-good service to users. Quality of service, therefore, helps address voice quality issues within a virtual phone system.

In a VoIP phone system, voice protocols are converted into data packets and transferred between two or more users. However, in order to obtain high call quality, these data packets need to arrive at the destination together and in the right order. And that’s where VoIP QoS comes into play as it sorts out traffic by dedicating resources where needed.

Is QoS needed for VoIP?

VoIP calls can be prone to jitter, latency, and packet loss issues which lead to bad audio quality, network congestion, missed or jumbled audio, dropped calls, etc. And for any business, this is a major issue because it interferes with your teams’ ability to offer uninterrupted service. Important business communications revolve around:

• Sales calls and demos
• Client and lead generation
• Customer success and customer support
• Technical and IT support
• Remote team management
• Internal business meetings
• Meetings with clients and business contacts
• Employee interviews

Network congestion can easily affect the quality of these calls, which in turn, leads to misunderstandings, frustration, low brand trust, low productivity, and more. Without QoS, VoIP calls are not functioning optimally. And that must be addressed.

Troubleshooting VoIP Call Quality with QoS

So, what does QoS do for VoIP phone systems? Routers generally handle data packets via a ‘first in, first out’ order. And all traffic is given the same level of priority. This means that all traffic from every device (phones, computers, mobile phones, etc) on a network get the same level of priority.

When bandwidth usage is high — too many people using the internet — these data packets can end up in long queues. Call quality competes with other applications running on the network. This is true for employees working within an office or remotely.

So, naturally, this affects voice call quality and successful VoIP deployment.

VoIP Quality of Service helps balance out how much bandwidth is needed for a certain type of traffic or certain devices. In other words, it spreads out the available bandwidth across devices and applications to ensure the right traffic gets through hassle-free.

VoIP QoS Settings & Requirements

So, what does your business need to do to ensure high call quality? Here, we will go through QoS settings and requirements to be aware of and best practices your business can implement.

VoIP Standards for High Call Quality: QoS Requirement

In order to improve VoIP call quality, you will need to set up QoS accurately. For good VoIP call quality, Cisco suggests these VoIP standards:

Understanding QoS Settings

Your business needs to troubleshoot VoIP issues to ensure optimal service. Let’s take a closer look at what these recommendations and settings mean.

DSCP EF
DSCP is short for Differentiated Services Code Point and EF is short for Expedited Forwarding. This model is designed to provide resources to reduce latency (delay) in traffic. In other words, this value sorts through traffic to prioritize VoIP traffic, leading to better, less interrupted call quality.

Packet Loss
Packet loss is the number of packets that get lost during transmission. More than 3% packet loss means low audio quality. Faulty routers, loose cables, and wires, low bandwidth, or poor WiFi signals can lead to packet loss.

Latency
Latency is the delay between the time the speaker speaks and the receiver hears them. Fix latency to avoid users speaking over each other or missing important pieces of audio.

Jitter
Jitter refers to a data packet arriving after the rest of the packet. Data packets may take different paths to reach the destination. This way one or two packets may reach later than the others and this can cause missed calls or jumbled audio. Fix jitter to ensure all packets arrive accurately and voice quality is maintained.

Bandwidth
Bandwidth for VoIP refers to the rate at which data is transmitted or transferred through an internet connection. Lower bandwidth leads to slow speed and low VoIP call quality.

How to Set Up QoS for VoIP?

The first step to setting up VoIP QoS for your business phone system is to reach out to your internet provider and VoIP service provider. These sources can provide exact guides on how to prioritize voice traffic.

Next, implement those suggestions and other call quality best practices. Work with your IT team to make sure everything is set in place for optimal call quality. You may even educate your employees on using other services (streaming services) while working.

VoIP Call Quality Best Practices

Here are the top VoIP call quality best practices to ensure your phone system works efficiently and calls are not interrupted:

1. Check and upgrade your internet speed: Make sure your network has enough bandwidth to handle call traffic. Regularly test your internet speed.

2. Upgrade cable connections: Use wired Ethernet connections such as a Category 6 certified cable. These cables can offer low latency and can support high levels of phone communication and data transfer.

3. Check network and equipment configuration: Network and equipment that are not appropriately configured can lead to disruptions and low call quality.

4. Test network connections regularly: Check ping, jitter, latency, and bandwidth regularly for network congestion.

5. Upgrade your VoIP provider: If your service is still affected despite troubleshooting, then it may be time to find a new phone service provider. Research providers to understand what services they offer and how they can help with VoIP call quality issues.
