I installed the CME on the 2851 router, the version of it is 4.1(0). Under this environment., the customer installed two VT Camera II. I have confirmed that the video function had been enabled, and the video enabled icon had already been shown on the IP phone screen.
After I use the command â show ephone registeredâ , it shows as follows:
ephone-7 Mac:001E.136C.348D TCP socket: activeLine:0 REGISTERED in SCCP ver 12 + Video and Server in ver 8
mediaActive:0 offhook:0 ringing:0 reset:0 reset_sent:0 paging 0 debug:0 caps:8

IP:172.19.29.110 3699 CIPC keepalive 24 max_line 8
button 1: dn 20 number 2008 CH1 IDLE
But when I make a call between two IP phones, Phone with the DN â2110âonly shows local window and Phone with the DN â2008â only shows remote window.
I`d like to know how to resolve this kind of problem. Could anybody please help me about that? Thanks a lot!
Should have picked this up earlier - the version of CME video firmware is different on the two phones and there doesn't appear to be any tftp statements and load statements in your config. I want to make sure you are running the correct release of firmware for 12.4.15T
Please do the following -
go to this URL
Since you are running 12.4.15T, this runs CME 4.1. Download the following zip file which contains all the phone loads and files for CME 4.1
Once the file is downloaded, open it up and extract the following files , then copy them across to the router's flash -
On the cme router, you need the following commands applied
Once these commands are added, go into telephony-service and add -
load 7941 SCCP41.8-2-2SR1S
no create cnf
Then reset the phones so they upgrade to the correct firmware. Once they have rebooted and upgraded, check the ephone versions and try the video calls again.
