Splitting an inbound trunk across several domains

[TomH]

I have external calls for a single sip gateway coming into a single trunk.

 

Right now I can make the trunk visible to all domains and set up seperate dial plans for each domain. The issue is the calls always go to the domain the trunk is in and the service cannot resolve the extension of the other domain.

 

So if domain primary.com wants all calls to 1111xxxx, where 1111 is the domain extension prefix, it works if the trunk is in primary.com.

 

But if a call comes through for 2222xxxx where 2222 is the domain prefix for domain alternate.com the service cannot resolve it. Even though there is a dial plan for 2222 in the alternate.com domain using the primary.com domain's visible trunk.

 

I am trying to avoid having a SIP gateway for each domain is there a way to route these external calls to the proper domain based stricly on the extension number prefix.

Usually those problems can be solved using the tel:-alias feature (if you give an account an alias name starting with "tel:" then is has a system-global scope). The PBX will then send the call into the right domain automatically, no need for an external proxy doing that job. See http://wiki.pbxnsip.com/index.php/Inbound_Calls_on_Trunk.

That did the trick.
