If a PBX is SIP compatible, then it will generally be immediately compatible with our SIP trunks.
The most important features for testing the compatibility of a PBX are:
- Ability to set registration time at 120 seconds (halves to 60s) where registration is required for inbound calls
- Ability to enter a username and password for authentication on outgoing calls
- Authenticate OPTIONS pings as failure to have this will result in the PBX being blocked.
If your PBX is not SIP compatible (i.e a legacy PBX), then it may still be compatible with a SIP to PSTN Gateway connected to the PBX, such as those made by Vega/Sangoma.
Please call us for confirmation if you plan to connect one to the service.
