What Are SIP Trunks?

With the upgrades on many phone systems occurring, one new term that has started to be used more frequently is SIP trunks. In this article we will dive into not only what SIP trunks are, but how they benefit your business and interact with one of the most commonly utilised phone systems (the pbx system).

What Is SIP Trunking?

SIP trunks are an upgrade for your phone systems, which allow for you to connect your office directly to the public phone network through a broadband/IP connection. This is widely available as a replacement to the archaic ISDN network which we all once relied on, and it is the medium by which businesses can operate with VoIP (Voice over Internet Protocol) technology. For background knowledge, VoIP is technology which allows us to essentially utilise phone services over the internet.

What Are The Benefits of SIP Trunking?

When you transition to SIP trunking in your business there are many benefits which you can count on, and here are just some which your business can make the most of:

  • Lower Monthly Line Rental – Say goodbye to high line rental fees with SIP trunking
  • Lower Call Charges – Due to high competition between providers the calls costs have been greatly reduced (more savings for your business).
  • Customer Service – SIP trunks allows for more international and geographic numbers to be added, leading to lower call costs for customers and improved customer service.
  • Moving Offices – SIP trunks allow for you to move to different premises but keep your existing number.
  • Flexibility – You can upgrade your trunk to have more phone lines. By adding more channels to your SIP trunk, you can increase your ability to cope with more incoming calls.
  • No Gateway Requirements – You won’t have to buy and manage VoIP gateways as the SIP trunks remove the need for this, ensuring all phone calls come in IP form.

How They Link With PBX Systems?

As mentioned previously one of the more popular phone systems for businesses is the PBX phone system. So how do SIP trunks and PBX systems link up? Typically, the PBX system actually uses SIP to connect to VoIP. Once you have SIP trunking in place you can easily use it in-line with your existing PBX system to continue using voicemail, automatic call distribution and call transferring, without the need for any additional changes.

The Importance of These Systems in the Internet Age

The internet age has increased our need for speed and accuracy, especially in the world of business. This is why SIP trunking is so vital for businesses, it ensures that businesses can operate highly effective phone systems without hitches or waiting times, and most importantly it removes the importance of location, something else which the internet has almost rendered obsolete.

There are some alternatives to using PBX and SIP trunking such as PSTN technologies like T1, PRI and analog lines, but there is little question that if you are looking for the very best set-up for your business, a PBX system which uses SIP trunking is your best bet.
