What is SIP trunking?
SIP (Session Initiation Protocol) sounds really technical and scary, but we promise it’s just new technology designed to bring your business into the future and boost efficiency.
In simple terms, SIP Trunking is a type of VoIP (Voice over Internet Protocol) that lets you use your existing phone system and handsets to set up multiple phone lines. It’s the future of telephony for businesses needing phone lines and numbers for tens, hundreds or thousands of employees.
SIP trunking uses high-speed broadband to create virtual telephone lines, rather than relying on the old-style physical copper lines to connect you. It’s based on completely different technology from traditional phone systems like ISDN and instead, your voice calls are transmitted using the same data connection that sends your emails, images and documents.
You just need a fast internet connection, which you’ll use for both voice and data, and an internet-enabled PBX (Private Branch Exchange).
Is SIP trunking right for my business?
As always, our dedicated team are here to help, but as a rough guide, SIP trunking is likely to be a good option if:
- All of your employees need their own phone lines
- You operate on more than one site (including remote workers who do their jobs from home)
- You already use a fast business broadband connection
- You’re thinking about upgrading from ISDN
I’m an SME, is SIP trunking right for me?
If your business or SME is smaller, with only a handful of employees, a multi-line phone system might be a better option for you.
Benefits and features
Switching to a SIP line allows you to reap the benefits of a traditional phone system, and so much more.
Always have a Plan B
SIP trunking relies far less on physical infrastructure than traditional phone systems, so it’s set up to cope with natural disasters, network failures and more. You can easily re-route inbound phone calls to a different location without changing your number.
Free site-to-site calls
For businesses with multiple sites, or those with employees working remotely or doing their jobs from home.
Save lots of money
Most businesses switching to SIP trunks will save a substantial amount on their phone bills. It’s especially cost-effective if you make a lot of long-distance and international calls, because all calls made over the internet are treated as local.
Use your existing phones
It’s simple to set up, and usually there’s no need to install any new equipment or handsets.

Installation and set-up
How many SIP trunk channels do I need?
That depends on how many phone lines your business uses at any one time. You’ll need a channel for each one. We can help you assess your usage, and recommend a plan based on your business activity.
But don’t worry – the beauty of SIP trunking is that it’s really flexible, so if you need to add more channels further down the line, it’s easy to do.
