What is SIP Trunking and How Does It Relate to VoIP Phone Services?

Learn more about SIP Trunking and how it relates to VoIP Services.

Businesses and consumers use Voice over Internet Protocol (VoIP) for the rich features, amazing audio quality, and cost savings. It’s only been in the last decade or so where advances in technology have helped it surpass traditional phone systems. Despite its popularity, there are many things that current and potential users don’t know about the technology or service.


Take SIP Trunking, for instance. We’re guessing every person who has used VoIP has heard the term, but many are not aware of what it is. Today, we’re going to discuss SIP Trunking and explain how it relates to VoIP phone services.


What is SIP Trunking?

Session Initiation Protocol Trunking, referred to as SIP Trunking, involves business phone services that send data over the internet. That data would traditionally go through phone lines. Instead of plugging into a physical network, SIP Trunking operates as a series of virtual phone lines. Anyone with a phone number can receive the information sent through this virtual system without the hassle or expense of cumbersome hardware.


SIP Trunking vs Traditional Phones

Businesses spent many years with only one type of phone system available to them the Public Switched Telephone Network (PSTN). The network stretches across the entire country and utilizes copper wires to relay information. Thus, there must be a physical connection made on both ends, whereas SIP Trunking doesn’t have that limitation. Plus, a PSTN can only carry one channel at a time while the number of lines utilized by SIP Trunking is unlimited as long as you have enough bandwidth.


SIP Trunking and VoIP Services

There’s a common misconception that SIP and VoIP are the same thing. While they both play on the same team, their positions are different. VoIP is a broader term that refers to data that transmits over the internet. There are several different technologies and protocols utilized to make this happen, and SIP Trunking is one of them.


Advantages of SIP Trunking

Now that we’ve covered SIP Trunking and how it compares to PSTN and relates to VoIP, let’s take a look at a few of its advantages. As you’ll notice, it has the same benefits of Voice over Internet Protocol (VoIP).


Less Hardware

Since SIP Trunking uses virtual phone lines, there’s a lot less hardware involved. When your office needs a new phone line added, you don’t need to have a professional run a wire so that the new phone can connect to the system. Instead, only attach an internet-ready device for a quick and easy install.


More Flexibility

Ever since the invention of the telephone, workers traditionally sat at their desks to manage their calls. In today’s workforce, sitting around waiting for a phone call is a thing of the past. No longer are the days that you are tied to your desks to send and receive calls. SIP Trunking makes transferring numbers anywhere super easy as a person moves around throughout their busy day.


Simple Expansion

Gone are the days of expensive, time-consuming expansions. When time is money nothing takes more time than adding a new phone line. Thanks to, SIP Trunking adding channels to your SIP Trunk is as easy as making a call to your provider. As your business grows, adding channels give you more lanes to send and receive calls. Nothing more than a simple modification of software.


Single Network

In the past, you would need more than one network to handle all your communication needs.


  • Faxing
  • Voice
  • internet data


SIP Trunking consolidates all your communication options via a single network. In the event of a communication failure, there is only one point to examine. In a large office setting that has separate networks, if one goes down, other parts of the office will still have communication.
