Hi,
I am trying to configure interconnection between gateway which is using SIP and H323. Look at the diagram
non-ciscoGW------SIP--------ciscoGW1--------H323--------CiscoGW2-------PSTN
For the nonciscoGW is the SIP server. All the IP Phone will register to the SIP server. I want to enable all the IP Phones which are registerred to the SIP server to call PSTN. I was able to make it work, somehow. But after I did some changes It doesn't work anymore.FYI, all devices are in the same subnet.
Here are the configs

If I do a simulation call from GW1 to GW2/PSTN. I am able to by using csim sta 9XXXXXX. But when I call from IP Phone to PSTN it doesn't work. It looks like the GW1 is unable forward the call to GW2. because when I do any debug about voice. I did not get anything..ter mon has been enabled.
