Cisco CIPC dropping the calls

[Venkatesh 96]

We have a Cisco CIPC 8.6.6 always having problems when changed the laptop from win10 to win11 version. Calls are dropping in the middle of the calls. But not for every call only few calls it's dropping. It is occurring randomly. Please help me better solution to get this issue fixed.

CIPC is end of life since nearly 5 years!!! You should consider switching to Jabber / Webex App instead.
You can't expect to get support, for software this old and is even not supported on Windows 11.

In short: Running such an old and unsupported application is your own risk.

If it is occurring randomly it will be hard to detect. The next time it happens, please gather the log file from the CIPC endpoint and post it here so we can take a look. It may be that we will need to look at the CallManager trace file as well, but I'm hoping the CIPC log will show us what we need to know.

As @b.winter mentioned, it’s time to move to jabber which is the  replacement for CIMC, The CIMC has reached EOL quite some time ago. It’s evident from the original post that this issue has been observed after upgrading to Windows 11. There could be compatibility issues causing applications to malfunction.

Try running the application in compatibility mode and see if similar issues occur.

Additionally, when the call drops, check if the phone gets unregistered. Also, verify if something is happening with the laptop’s network, etc., to ensure whether the issue is stemming from the CIMC or if it’s a network-related problem.
