SIP Trunks

If you already have PBX installed at your office, then a SIP trunk gives you access to real-time communications such as VoIP.

By combining with your existing telephone network, a SIP trunk can replace your public switched telephone network (PSTN) and primary rate interface (PRI) devices – creating a single path for voice, video and data.

Openface SIP trunks are compatible with other data services – and adaptable to your current needs, as well as what you may require in the future.

We give you the trunk you need – and you have full latitude to customize it to your own needs.
You only need to call us if your lines are down.
