Phones terminates unexpectedly

[Bura]

Hello Team,

We have recently come across the issue of phone to terminate unexpectedly(It happens randomly and to almost all extension from time to time, to some extensions it can be after answering calls then the call terminates, to others it last for couple of seconds)

IP phones in use are CP-7821 and CP 7811

CME in use is Cisco isr 4331. What could be the issue and how to resolve it. Below is the running configuration.Kindly assist as it has been months and we have not found any reliable solutions despite lot of troubleshooting steps we have already tried

If your configuration is up and working (although maybe a little thin on the voice service voip/sip section), then there are likely no significant issues with it. Please run a debug ccsip messages that is going into logging and wait for the issue to recur. Once the issue recurs, capture the information about the call (device, calling party, called party) and also the output of the debug and post it here. We can take a look to see if we can locate the issue.

When you post the output of the debug, please put the information into a text file and attach the file to your post (rather than pasting the debug into the post window). That will make it much easier for us to look at.
