Re: MOH CCM 3.1

The IPVMSapp.exe runs as the "IP Voice Media Streaming Service" on your callmanager servers, it is the server process for the conferece bridge device (CFB_), MTP device(MTP_, and MOH server (MOH_). If that service stopped, or the kernal mode driver (listed under devices in device manager in win2k, then your CFB, MOH, and MTP devices would unregister. Try re-starting the service to see if your MOH returns. If it does, turn on detailed traces for the IPVMSAPP service (under /ccmadmin->applications->callmanager serviceability->trace->configuration) and log the traces until it happens again. When it happens again, open a TAC case and attach all available traces from this service and the time of the unregister message similar to the one you posted here.
