also all tftp statements included but so far i could not register even one phone successfully i noticed that phones have a higher Software version that is compatible with cme 10.5 could that cause a problem or it is something else ?   

thanks and appreciate the help in this issue

Hello Amer,

Hello Amer,

Could you check below things and let us know

1. Are the phones able to get IP address and tftp server from DHCP? Check under phone setting or on switch using "show cdp neighbour detail"

2. What is the current firmware version on IP phones? you can check under settings

3. run below debug and power reset a phone. Wait for few minutes and check if you see any activity in the logs. Share the log if you see tftp events and MAC of phone which was reset.

You can try to perform

You can try to perform factory reset on one of the phones with issue. These are brand new phones or they were used before with another CUCM/CME before?

The CME and the Phones brand new and the phones work just fine before trying to register it to the CME, the moment you try to register it keeps displaying "registering" and when trying to access the setting the message " xml parser error" appears, and i tried to register more than 1 phone and the problem keeps showing up on every phone am trying to register

thanks

Upgraded 7811 to the latest firmware available.
