SIP trunks and inclusive call bundles

Let SIP Trunks unleash your phone system

Traditional fixed or ISDN lines are costly and are no longer being sold from 2020, ahead of the service being shut down in 2025. That’s where SIP Trunking comes in. SIP is a type of VoIP (Voice over IP) service that enables you to use the power of your broadband internet connection to replace traditional PSTN or ISDN lines. Essentially, SIP Trunks enable you to make and receive calls over your internet connection at a fraction of the cost of traditional fixed lines.

SIP Trunks can be massively cost-effective and deliver huge savings on traditional phone lines. You can make huge savings compared with traditional phone services – with FREE inclusive calls. Northern Telecom SIP Trunks come with unlimited inclusive calls to 01, 02, 03 and 07 numbers.

SIP Trunking can unleash the power of your existing phone system – which is great news, because it means you don’t necessarily need to invest in a new system to take advantage of the massive savings and inclusive calls that come with a SIP Trunk. All you need is a compatible phone system. If you’ve purchased a phone system in the last few years then the chances are it’ll work with SIP Trunks. Even if your current system isn’t compatible, there are plenty of cost effective solutions, including using a new phone system, or pointing your SIP Trunks to a ‘hosted’ telephone system in the cloud. You can find out more about hosted systems here.

You can easily move your existing numbers to SIP Trunks – and we’ll give you a guiding hand every step of the way.
