What is the solution for this?

Hi Mohammad,


Could you collect the following and attach it here:


++     show run

++     show flash

++     show version

++     MAC address of the IP Phone.

Enable the following debugs, factory reset the phone and capture the output:

++     debug ephone register

Properly configure CME to provide the firmware and XML configuration files to the phone.


The firmware is erased from the phone when you perform a factory reset. The phone needs to be able to retrieve this from the CME TFTP server. Once that is done, it will then look for it's configuration file. This needs to be generated once you have properly configured the phone and directory numbers.
