                   HI, I need to add 6945 ip phones but my current version on CME is 8.6 which's not compalitble to 6945 IP phones. I just downloded the complete CME verion 8.8 zip files which around 303MB. I want to know how to upgrade my cme 8.6 to 8.8,

Appricate if some body comes with full proper step wise procedures.

CCME version is determined by the IOS running on the router..You need to upgrade your IOS to version 15.2(1)T.

Have a look here at the compartibility matrix
