Hi Avijit,

From the debugs, it seems like the phone is indeed getting the config file.

 

Oct 17 06:08:17.029: TFTP: Looking for SEPB07D47C131AA.cnf.xml

Oct 17 06:08:17.033: TFTP: Opened flash:/its/vrf1/SEPB07D47C131AA.cnf.xml, fd 4, size 1534 for process 62

Oct 17 06:08:17.041: TFTP: Finished flash:/its/vrf1/SEPB07D47C131AA.cnf.xml, time 00:00:00 for process 62

The next step is the phone should send a register message to the CME IP :172.16.252.123. You can check this by taking a packet capture from the phone. Also can you provide the "show run".

Can you provide the below debug after resetting the phone once:

debug tftp events

debug sccp messages

debug ephone register

You have mentioned that you are able to register 3 other models. Are they sccp or sip ?

Can you try deleting the ITL/CTL on the phone if any using the below procedure (It will be similar for 6901 phone but options might differ) and if the issue persists, let me know what you see in the status message on the phone.

you could follow the below steps and do a factory reset. But pls make sure that you have a valid DHCP in your network. Else the phone wont come up.
