Known issues upgrading IOS on rouerts running CME?

[robertjo24]

Is anyone aware of any issues that would occur from upgrading the IOS on a router running CME?

We upgraded IOS on our 2811, and we seem to have issues changing configurations on phones from the CCME.html.

If you upgraded the IOS, you also have to upgrade your GUI files that are stored on the routers FLASH. The versions must match.

When you upgraded your IOS you also upgraded your CME version. You will need to upload to flash the CME files that CISCO has for the IOS version you are running.

The files include phone loads and other files needed for CME to run properly as pndscm mentioned above
