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
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.
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.
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
source-address 192.168.0.1 port 5060
load 7960-7940 P0S3-08-5-00
Also, if your ISR acts as TFTP server, don't forget to specify tftp commands in config mode (7960 phone example)
Then hard reset phone , and it will load anyting that you specified in load command
