Hi,
I have a situation, where I send subscriber calls to an external PBX (for enhanced routing) and need to have a fallback to route calls to
local subscribers, if the external pbx fails.
The only way I could do this was with a RouteList / Routegroup, and have the same CUCM system as a loopback trunk.
Now the originating partition and terminating partition are different, when calls go over the looped trunk....
But is this a bug in CUCM 5? Is the SIP stack not supposed to reject an INVITE that it sent out if it sees it coming back in ?
Ideas / Comments ?
