My CP-7821 phone will not register.
I am attaching my Router 3945 15.4(3)M3 CME 10.5 config and my switch config.
My phone cp-7821-k9= v04, s/w must use 10.3(1) or later. Phone active load is sip78xx.11-5-1SR1-1 and firmware on CME is sip78xx.10-3-1-12.loads.
I have uploaded the zip files and not the cmterm-78xx.10-3-1-12.k3.cop.sgn.
The phone takes IP but won't register. I turned on debugging and attached it in the end of the document and all I get is TCP debugging the registration process doesn't even start.

show voice register pool all
nothing
Normally the phone should take the firmware in CME. According to Hardware version 04 the firmware sip78xx.10-3-1-12.loads is recommended.
Maybe something wrong with the config. Any help would be appreciated.
Thank you

Hello! If I will be in your situation, I would erase startup config on RT, SW and hard reset phone.
And tried to simplify config, left only voice register global, pool, dn, and dial-peer.

Thank you
I wonder if it is possible to register the phone with CME 10.5. I don't think it is possible to downgrade the phone to firmware 10.3.1. It is either that or the config

You can specify phone firmware in voice register global
voice register global
mode cme
source-address 192.168.0.1 port 5060
max-dn 5
max-pool 5
load 7960-7940 P0S3-08-5-00
create profile
Also, if your ISR acts as TFTP server, don't forget to specify tftp commands in config mode (7960 phone example)
!
tftp-server flash:P0S3-08-5-00.loads
tftp-server flash:P0S3-08-5-00.sb2
tftp-server flash:P003-08-5-00.bin
tftp-server flash:OS79XX.txt
tftp-server flash:P0030801SR02.sbn
tftp-server flash:P003-08-5-00.sbn
Then hard reset phone , and it will load anyting that you specified in load command
