SIP Line vs. SIP Trunk: What’s the Difference?

Source: DepositPhotos.com - Lic#20018711 ID#27446420

Many businesses offering local and international services often wonder if there is any way to modernize and enhance communications without receiving overwhelming bills each month. Well, SIP trunking and SIP lines make a fine solution. Let’s look at the difference between a SIP trunk and line so you can get the phone system that works best for you.

SIP Line vs SIP Trunk: Understanding the Difference

Oftentimes the terms SIP line and SIP trunk are used interchangeably. However, there are two components that work together and are not the same thing. Here we explain what each term entails so you have a better understanding.

What is a SIP Line?

SIP lines are also called SIP channels or SIP sessions. A SIP line is an element of a SIP trunk through which data can be exchanged between two points. A SIP trunk holds large numbers of SIP lines or channels. During calls, a SIP channel is the unit’s capacity to support an incoming or outgoing call. In other words, each call uses one channel.

And so, companies needing SIP lines are more than satisfied by one SIP trunk. However, exactly how many lines your business needs depends on the number of concurrent or simultaneous calls you handle per day. SIP providers offer a variety of plans:

  • Unlimited channels
  • Unlimited channels with a fixed number of session minutes
  • Fixed number of channels with unlimited minutes
  • Multiple trunks for multiple offices on the same network

What is a SIP Trunk?

SIP trunks connect your business’ private branch exchange or PBX system to the internet. In other words, it converts your traditional phone system into a virtual or digital version.

As noted above, a SIP trunk holds SIP channels and makes concurrent SIP calling possible. In VoIP phone systems, a SIP trunk can hold about a hundred SIP channels. These lines can be distributed across different departments, devices, and so on.

SIP trunking enables your business to make and receive calls over the internet instead of a traditional POTS line. This way, this method of communication supports both traditional as well as VoIP phone systems. With SIP trunking, you can transmit voice, video, text, and other unified communications.

Benefits of SIP Trunking

Why should your business consider SIP trunking as part of your communication system? Here are some ways SIP trunking benefits businesses:

1. Unified Communications: With SIP trunking, you can handle voice, video, and text transmission through one platform. Additional services are not required.

2. Low Cost and Set-up: SIP trunks don’t need extensive hardware or software to function. A reliable internet connection is more than enough.

3. International Coverage: With SIP trunking, your local and international business calling bills reduce tremendously.

4. Scalability: You can always add extra SIP lines to your SIP trunk if/ when needed. Again, there is no extensive set-up or installation required.

5. Tools for Better Customer Service: By providing voice, video, and text communication, you can enhance customer support by adding video conferencing, text messaging, and file-sharing.

Does Your Business Need a SIP Line or SIP Trunk?

The decision really isn’t one or the other. This is because SIP channels work within a SIP trunk. The real question is, how many channels does your business need?

A SIP trunk can host multiple SIP lines, allowing for multiple concurrent calls to occur simultaneously. In other words, if your business has 250 SIP lines, it can handle 250 calls at the same time. Each call takes up 1 SIP line.

Similarly, SIP trunking prices or monthly fees will depend on how many lines your SIP trunk holds. To determine this, you will need to know how many incoming and outgoing calls occur during a day. Work with your sales, marketing, and customer service teams to get an approximate number.

If your business does not receive or make a large number of calls per day, then you may choose to have a few employees or small teams on each SIP line. Additional SIP lines can be added later.

In this comprehensive post, we will explain Session Initiation Protocol (SIP) and its important features.

What is Session Initiation Protocol?

Session Initiation Protocol (SIP) is an internet signaling protocol that is used to initiate, maintain, and terminate real-time voice and video communication. An internet protocol is a set of rules for routing packets of data across a network. SIP is often used for mobile phone calling over LTE and in IP telephony systems.

It enables businesses to take their communications to the next level, by enabling not just voice-sharing but video conferencing and text messaging as well. Unified communications are made possible for an organization through SIP.

Important SIP Features

Note that SIP is a signaling protocol. In other words, it doesn’t handle the specifics of multimedia sessions. Other protocols such as the Sessions Description Protocol and Real-Time Transport Protocol handle media details and data delivery respectively.

Session Initiation Protocol initiates a call between two or more people where the SIP client establishes specifics of the request. The other party can choose to accept or reject it. This transmission is done securely through Transport Layer Security (TLS).

Additionally, Session Initiation Protocol makes it possible for users with different service providers to interact and communicate. It can boost your IP telephony call with a process called SIP trunking.

Session Initiation Protocol versus Voice over IP

SIP and VoIP are often used interchangeably and therefore, it is important to understand the difference between these two types of technology. See below:

SIP Trunking Voice over IP Tech
Signaling protocol within VoIP Family of technologies related to communications
Multimedia transmission Only voice messages transmitted
Requires only a modem VoIP devices need to be connected to a computer
Uses a peer-to-peer system to handle large amounts of data Uses a central network to organize and transmit traffic

Benefits of Session Initiation Protocol

Why do businesses benefit from SIP trunking and why should you consider this service for your communication system? It’s simple: SIP and SIP trunking can boost and enhance communications in a multitude of ways. It is not only cost-effective but provides phone solutions to improve internal and external communication. Here are some of the top benefits of SIP trunking.

A HIghly Cost-Effective Service
SIP calls are routed over the internet and by doing so, this gives you the ability to contact local and long-distance contacts for cheaper calling rates. Pricing for a SIP trunking service is pretty straightforward. You sign up for a monthly subscription and your bill remains predictable. Furthermore, most SIP providers do not require you to sign long-term contracts. Check out our detailed analysis of SIP trunking prices for your information.

Tools to Expand Internationally
Part of growing your business globally involves creating strong communication channels between your company and its customers. SIP trunking paired with virtual phone numbers is a great solution for businesses looking to expand their reach into international markets. You can reduce your calling costs while providing convenient (and even free) ways for customers to connect with you through local numbers and toll free service.

One Platform for All Communications
You can transmit voice, video, text, and more via SIP channels. This technology makes multimedia communication possible from one platform, instead of having it spread across 4-5 different services or software. This can help increase office productivity and reduce costs that can build up from different platforms.

To decide whether your business needs SIP trunking or VoIP technology, you must first understand what these communication services are and how they differ. Here we will discuss in detail how these two types of technology operate so you can make an informed decision when choosing between them.

Difference Between SIP Trunking and VoIP Technology

SIP and VoIP are often used interchangeably, which is why they can be misunderstood. SIP stands for Session Initiation Protocol while VoIP stands for Voice over Internet Protocol. Both of these services provide foundations for IP technology. That is, they enable users to make and answer calls over the internet (or virtual phone lines) as opposed to traditional phone lines or PSTN lines. But there are a few key differences that set them apart, let’s have a look.

What is VoIP? The Basics

Voice over IP or VoIP technology is a business phone solution that transmits voice messages over the internet. It converts voice into digital signals and sends them to the destination number or endpoint. To use this service, you will require a VoIP phone and VoIP system. Most providers will even offer you unlimited calling minutes as a better deal. And so, for basic voice communication, VoIP is an affordable and practical solution.

SIP Trunking Explained

SIP trunking enables the transmission of multimedia and unified communications over the internet. SIP technology builds on voice over IP to provide not only voice but other communication as well. That is, video messaging, text messaging, file and document sharing, and so on. SIP trunking, therefore, works as an all-inclusive phone solution.

For a business looking to provide multi-channel communication, SIP technology is an ideal solution. This is because it is more affordable than using multiple different platforms/services as all communication tools needed are located in one place.

SIP vs VoIP

Now for the difference between the two types of virtual telephony solutions:

1. Type of Sessions Transmitted — VoIP calls handle only one type of session and that is voice communication. SIP calls, on the other hand, handle multimedia sessions such as voice, video, text, etc.

2. Operation — VoIP calls operate only over an internet connection and need a computer to run the software. VoIP handsets, for example, must be attached and connected to a computer to be used. A SIP trunk, on the contrary, can work over any network; this includes ISDN, VPN, or the internet. Plus, SIP equipment can operate by itself and does not depend on a computer to function.

3) Handling of Traffic — Both systems differ in terms of how they handle traffic. SIP systems work along with an office’s private branch exchange or PBX system. These systems are designed to manage large amounts of traffic and data. You can also add an extra layer of security by getting a direct connection to your provider. VoIP technology, on the other hand, handles traffic from a central network, where a provider oversees everything. This is perfect for businesses that do not have the experience or time to manage their own systems. However, on the downside, such central networks can easily be overloaded by heavy traffic.

Choosing One for Your Company

Deciding whether your company needs SIP trunking or voice over IP technology depends on the type of communications you want to set up. The choice is not really one over the other because SIP is an advanced version of VoIP. Both services can boost your company’s phone system by offering more reliable and cost-saving options. Based on how you want to communicate internally and externally determines whether you need only voice or multimedia sessions. You can get both SIP and VoIP with United World Telecom.

When switching to a cloud phone system for your company’s communications, owners often have to decide between a hosted PBX and SIP trunking. Here we will discuss what these two types of service are so you can make the right decision based on your needs.

Hosted PBX versus SIP Trunking: Key Differences

In order to decide whether your company can benefit from a hosted PBX  or SIP trunking, it is important to first understand what each of these services is capable of achieving. Other factors to consider are:

  • Costs
  • Level of expertise required
  • Company size and calling (or call management) requirements
  • Security needs

But first, let’s look at these services and their benefits individually.

What is a Hosted PBX?

If you want a system handled and managed offsite, then a hosted PBX service will be more in line with your needs. Other terms for hosted PBX are virtual PBX, cloud PBX, and cloud phone system. A hosted PBX service is a service managed by a third-party provider and connects to a public switched telephone network (PSTN).

Benefits of Hosted PBX

Therefore, subscribing to a hosted PBX service means that your company does not have to buy or maintain any equipment or software to utilize the service. And so, you do not have to worry about high setup or maintenance fees. Additionally, you do not need to hire experienced IT professionals to manage the system.

A hosted PBX service will give you the opportunity to utilize Voice over IP services such as:

  • Call management tools to manage and route calls
  • Call transfer
  • Voicemail
  • Call recording
  • Interactive voice response (IVR system)

What is SIP Trunking?

SIP trunking also uses VoIP technology. SIP connects your existing PBX to the internet and enables the sharing of multimedia files such as voice, video, and text. Therefore, to use SIP trunking technology, you need to have an on-premise PBX system and a skilled and experienced in-house IT team to manage it.

Benefits of Using SIP Trunks

SIP technology is growing more and more popular with businesses because of the many advantages of using such a system. Here are a few benefits of SIP trunking:

SIP trunks replace traditional phone lines by helping you make and answer calls over virtual lines instead. This enables long-distance and international calling at cheaper rates. Therefore, SIP technology is often preferred for its affordability.

Furthermore, you do not need to subscribe to 4-5 different services to handle your office’s communications. SIP trunks allow for transmission for various types of data all in one place, making business communications easy to manage. This is also helpful in increasing overall office productivity and efficiency as employees spend less time learning new services and more time providing better customer support.

Key Differences Between Hosted PBX and SIP Trunking

Now that we have a better understanding of what each service means, let’s look at the key differences between having a hosted PBX system and SIP trunking as part of your office phone system:

Hosted PBX SIP Trunking
1) Setup Costs Low Low, if you own PBX equipment on-premise
2) Ongoing Costs $15-$50 per phone line per month $20-$50 per user per month
3) Maintenance and Expertise Handled by your provider Handled by your in-house IT staff
4) Expertise Required No, handled by the provider In-house IT staff must be experienced
5) Call quality and volume Great for low call volume Great for a large workforce and a high call volume
6) Flexibility Geographically flexible and self-reliant Depends on PBX program licensing and support
7) Company size and type Recommended for companies with <20 employees Recommended for companies with >20 employees
8) Security Depends on the provider’s standards More secure infrastructure

Choosing a Phone System

Deciding on a type of phone system for your business can be overwhelming. To simplify the process, pay attention to what your business needs and what your budget allows. For example, can you afford a skilled in-house IT team or do you want your provider to handle maintenance? Do you need a system that supports a low or high call volume and traffic? And so on. Determining your business’ needs will help you make a better choice. To get SIP trunks and PBX, call United World Telecom and speak with an expert.
