SIP trunks are changing the way make calls, replacing traditional ISDN products they are more resilient and cost effective, and, you don’t have to abandon your existing PBX…

SIP trunking is highly resilient, not only offering a stable, reliable and cost-effective foundation for your voice communications, but also providing a vital tool when it comes to disaster recovery. Calls can be re-routed automatically to an alternative path or location, whether to another connection within the premises, or to another site. The process is so quick that your service is maintained without interruption.

SIP trunks allow FREE on-net calls between multiple connected sites offering you fantastic cost savings, along with competitive call rates to all off-net and international calls.

Our SIP trunks are built on our own OPTIMUS platform over a resilient 10GB core network which uses two dual-node SBCs, and are load balanced (active/active) across our multiple carrier grade data centres.

It’s a complete solution, offering a reliable service supported by SLAs, at a cost that’s truly competitive.
