Friday I was working on a particular phone, and was having problems. In total, we have 3 7916's going into service, 1 to 1 user, and 2 to the operator. Both the user and the operator are going to be using Cisco 7975 IP Phones. I connected the power block to the device, and it works correctly, it lights up completely. However, the phone does not detect an expansion module being detected.
Furthermore, I have been attempting to navigate through all of the phone options i could find in CUCM, and was completely unable to find anything regarding any expansion modules. I attempted to locate help on the subject, and while the help stated I should be able to select an expansion module, I do not see the option anywhere on any page. Another tidbit of help wanted me to create a line profile using the 7960, however I feel that was outdated information and did not serve my purpose.
Can someone please help me get this resolved, so that I don't waste any more time than necessary trying to troubleshoot this?
