SIP TRUNKS: IP-based voice calls at lower cost

With SIP Trunking you can route calls over your business internet connection at lower costs, while also gaining access to enhanced capabilities.

does sip trunking work?

SIP Trunking connects your business to the Public Telephone Network (PSTN) by running a number of SIP channels over your existing internet connection, rather than needing a separate traditional PSTN or ISDN line. It provides increased flexibility, resilience and cost savings to businesses over traditional phone lines and negates the concern over the upcoming ISDN stop sell and switch off. Your business is usually able to keep your existing PBX and telephone numbers making this a straightforward and easy way for businesses to move to a low cost and future-proof voice solution.


We all have the best of intentions when it comes to disaster recovery but how prepared are we really? The cost of technical failure, data loss or missed sales can be severe, so arming ourselves with systems with built-in disaster recovery solutions are key to our survival. With SIP Trunking’s in-built disaster recovery mechanisms, every crisis moment is easily managed.  You can easily and automatically re-route calls anywhere, any time with a virtual phone line that can redirect calls to wherever you need them.
