I'm using a CCM 4.1(3) and i cannot register IP Phones 7906 & 7911. These are not available in 'Phone type drop-down list'. Is this CCM 4.1(3) can be upgrade to support these phones ? which patch ? how ?
No need to uninstall my friend :) Just install the new one and you should be good to go. Once that has been completed the 7906 will be available on the Device Defaults page.
Hope this helps!
