This may or may not relate to a thread that I posted earlier where the inbound route is followed for PSTN calls but not SIP calls coming from the same provider as the registered trunk.
If I have a trunk registered for example 123456@sip.supernettel.com , the server at sip.supernettel.com can successfully send a call every time, however if that server also sends calls via a second IP address, they MAY not follow the inbound route correctly. I have tested this in the following way.
inbound route trunk name is 123456 (example only) , registered to 123456@sip.supernettel.com
I can send a call from sip.supernettel.com , but dialing to the URI of 123456@www2.pbxes from xlite (registered to FWD) , yields a recording on an unrelated PBX.
This routing should work REGARDLESS of the originating IP, with the following case in point:
Many providers send calls from an IP address different from the registration IP address.
I believe what is happening is that the PBX server is allowing that inbound route to be used only from the IP address from which it is registered to for that particular trunk.
