Converting a Cisco 7912 SIP Phone to a Call Manager Phone

the major problem i have had in changeing the firmware is not having the current firmware. You have to upgrade your sip firmware on the phone to the latest version before changing it to SCCP. I would reccomend this first. then try this link.

Version and description:

The install program file name is cmterm-7912G-sccp.6-1-1.exe and the firmware version within the install program is CP7912060101SCCP050429A.SBIN

Post-Installation Details This executable file is to be run on the publisher and it will install one file:

After installation, open up call manager's administration web page and go to system -> device default You can verify the installation, by looking at "IP Phone 7912" and enter the new load name in the corresponding box. for example: CP7912060101SCCP050429A.sbin (in this case, the load version is 050429A)
