SIP Trunking is fast replacing traditional ISDN. It connects your PBX to the PSTN (Public Switched Telephone Network) via broadband, Ethernet or private circuit into our national network. Our SIP Trunks work seamlessly with all the leading IP PBX brands in the UK market, including Microsoft Lync.
SIP trunking vs ISDN
SIP has several advantages over ISDN, such as
- cheaper line rental and calls.
- add and remove lines, split calls etc.
- calls easily diverted.
- voice data convergence.
- easily divert calls to your home phone in case of emergency.
- ISDN fails because it is almost obsolete.
