I would also suggest debugging the signaling protocol being used for calls to/from this analog port or reviewing CCM SDI/SDL traces. If these are MGCP controlled, try to determine if CUCM transmitted a DLCX without first receiving a NTFY for the on-hook event (O: L/hu). Seeing a NTFY with O: (observed event) L/hu (line package/on-hook transition) come into CUCM from the gateway for your analog endpoint hung up -- if a DLCX to the gateway follows that event, then the disconnect was initiated from the analog endpoint.

Hope this helps.

Dan

You could switch on 'debug vpm signal' and log the debugs to a syslog server or to the buffer. You'll need to increase the buffer size.

Another trace that you can use after the call completes is 'show voice trace a/b/c'

I have some analog ports that keep dropping calls and I was wondering if there was a way to turn on a log file to record specific analog ports so I can see if Cisco is disconnecting them or the device attached to the analog port is causing the disconnect.



Thanks
