I have multiple sip trunks on my system and would like to route calls from particular trunks to specific outbound routes.
Basically I have a couple of 3rd party systems that have SIP trunks as well as my main carrier SIP trunk.
I want 3rd party A to be able to dial only extensions 3xxx, and 3rd Party B to only dial extensions 1XXX.
I have been looking for some time now and just cant seem to find anything that hints on the availability to do this. Can anyone point me in the right direction?
