SIP Trunks

Future proof your business and move to IP Technology


Replace your ISDN and keep your Telephone System

What is SIP Trunking?

Session Initiation Protocol (SIP) Trunking is a way of providing telephone lines using data rather than fixed lines. It gives you the ability to make outgoing and incoming calls using IP technology without needing to completely replace your current telephone system. SIP is the ideal replacement for fixed lines and offers greater flexibility and resilience whilst being at a lower price point.

What do you need to move to SIP?

SIP uses VoIP technology to make and receive calls so you will firstly need some form of connectivity. We recommend high speed fibre or if you need more than 20 concurrent calls we recommend a dedicated connection like Ethernet.
You do not need to move your telephone system to a hosted system as SIP provides you with the ability to use your existing service. However, you need to make sure your telephone system is IP Compatible.

We understand that moving to IP can sometimes be a big step for a business so we’ve taken the time to ensure our staff can help you move your numbers to a new IP network as seamlessly as possible. We also offer some great features and benefits, just take a look at some of them below.

Adoption of Microsoft Teams has been huge during the lockdown and growth is likely to continue as more companies adopt a work from home policy.

Subscribers to Microsoft Teams have the option to turn their Teams account into a hosted phone system by either adding an MS call plan @ circa £12 per user or using the Direct Routing option.

With Direct Routing you would be taking a SIP Trunk service from an actual telecoms provider. To this end we have recently launched SIP4Teams a dedicated, feature rich and competitively price SIP Trunk service for Microsoft Team.
