SIP Trunks & Connectivity

SIP Trunking is the standards-based replacement for traditional ISDN. It connects your PBX to the PSTN via broadband, Ethernet or private circuit into Gamma's national network.

Our SIP Trunks work seamlessly with each of the leading IP PBX brands in the UK market including Skype for Business and Alcatel-Lucent Enterprise.

Five reasons to switch to SIP...

1 - Save money on call costs and line rental

SIP delivers less costly, more reliable connectivity than ISDN over an IP connection. It can save up to 50% on line rentals and 25% or more on call costs.

2- Free internal calls and great features

Perfect for medium or large organisations with multiple sites, not only will you save on your line rental and call costs, but you'll get free internal calls within your organisation and a whole host of great features.

3- Scale up and down when you want

SIP trunks are ideal if you are moving, upsizing or downsizing and want to keep your existing numbers. Scale up lines during busy periods and back down again afterwards. You can add lines, take them away, split calls at any time. You are always in control.

4- Built-in Business Continuity

SIP trunks can handle emergencies easily. They are inherently disaster recovery / business continuity ready, letting you reroute calls to an alternative location quickly and easily.

5- Compatible with Skype for Business

Our SIP trunks are integration tested and approved to interoperate with Microsoft Lync / Skype for Business, allowing you to directly connect to the platform to make external calls.
