SIP Trunking

SIP Trunking is an Enterprise Voice over Internet Protocol (VoIP) solution. It optimises your secure data connection – your Managed Internet Access or IP Virtual Private Network – so that you only need one connection for voice and data. SIP (Session Initiation Protocol) Trunking plugs into your existing phone system, replacing your traditional voice service such as ISDN30.

SIP trunking can help you save money by using your data network to handle all your calls so you no longer need separate phone lines.

If you’re looking for a full end-to-end voice service, where we sort you out with everything Cloud Voice is the solution for you.

If you need the flexibility and control of your own phone system – and either already have a phone system or are happy to buy, run and manage the phone system yourself – SIP Trunks are the right choice for you.

Sip Trunking

With the rapid decline of traditional telephony technology, ISDN, SIP trunking is fast-becoming the next-generation communications solution of choice. In fact, BT have recently announced their plans to cease all ISDN circuits by 2025!

On top of this BT have also confirmed that, as of 1st September, they’ll be increasing the cost of indirect access (IDA) calls by 0.2718 pence. A change that any business using an IP communications solution can easily avoid.
Yet whilst voice services are essential, many business forget that high-quality connectivity is key to a reliable, resilient communications solution.
