My problem was the VX900. The CME IP source address was a loopback (192.168.20.1) and the CME router was the default gateway (192.168.1.1) of the network the VX was on. I could call from a PBX switch through the VX to the CME, but I couldn't call back. The problem was the VX was seeing the default gateway as the inbound calling party not the loopback address. To fix this I made the SIP inbound the default gaetway and everything worked fine. I guess you could also just make the CME IP source address the default gateway. I hope this helps someone, because this is the only place I could find anything about making a VX and a CME communicate. If you go to the CLI of the VX Enable->Trace all (Trace none, to turn off) and then call you can see what the issue is.

[quote]I'm sure the original poster has long figured this out, but recently I've run into a similar issue and found the cause to be the pattern on the VX900 not being syntactically correct for the SIP messaging.   For example, I had {$$$}{$$$$} for incoming matching, but in order to preserve the id of "e.164num@ipaddress" the pattern should be {$$$}{$$$$}@+[/quote]     Having similar issues, could you specify your last post.
