Compatible systems
Currently supported for SIP trunking: Panasonic and Avaya IP Office PBXs. Ask us before assuming another system will work.
SIP trunks
SIP trunks replace ISDN or PSTN circuits on an existing phone system. A practical option if you want to keep kit that still works and still be ready for the January 2027 switch-off.
What SIP trunks are for
Instead of copper ISDN channels, your PBX connects over the internet. You can add call recording, time-of-day routing and other features, and combine trunks with hosted seats at other sites as one system.
Number porting
Bring your existing geographic and non-geographic numbers across. Typical timescales apply (~4 days PSTN, ~22 days ISDN — estimates, not guarantees).
