You'll need to be more specific about how calls drop, what you hear, what shows up on your IP phone, if it has a pattern, how long it has been happening, when it started happening, what changed, what version your gateways are on, what version CUCM you're on, what type of PSTN connection you have (CAS, PRI), error messages from CUCM or the gateway, anything.
User hear beep beep...tone when calls are getting disconnected. Users are not getting any error message on phone when calls are getting disconnected. User has to redial the call.
Calls are getting disconnected intermittently. There are three E1 PRI terminated on VWIC2-2MFT-T1/E1 card. MGCP gateway's ios part no is S28NSPSK9-12403
cisco 2800 SP services. cucm version is 5.1.3c
I don't know how to check any error message related to pri line in call manager. I had observed sometime layer 2 of all three pri lines flaping, but i am not sure whether calls are getting disconnected due to layer 2 flapping or is there any problem in the config of the mgcp gateway or call manager.
Herewith i am attaching config of mgcp voice g/w and debug output.

answer. Be sure to read the whole thing or e...
