Connecting your PBX system to the network, with reliable, secure SIP trunking from Nexus IP.
A SIP Trunk is the virtual link between your PBX and the PSTN over the internet. It allows you to make outbound calls and receive inbound calls using an IP connection (VoIP) rather than a traditional ISDN/PSTN line. With ISDN being phased out and moving to all-IP, SIP Trunks are essential to keep your telephone system operating.
At Nexus, not only do we specialise in installing telephone systems, we can also connect your existing PBX systems to our network to complete and achieve the system’s full functionality.
Due to the 2027 BT switch-off, moving your lines from ISDN to an IP-based communication service is essential, whether you’re still using ISDN or moving from an analogue PBX, switching to SIP is the way forward.
