I recently upgraded my CCME3.3 to 4.0(2)so that i can use the video conferencing features on my CCME. After upgrading CCME and IOS, most of the IP Phones lost there images and displaying an error "Protocol Application Invalid".
So i degrade back my CCME & IOS versions.Then again i loaded back the IP phone images.
What's is the problem? Is it i can able to upgrade CCME without having this problem?
