Matthew,<br><br>Did you keep any hardcopy of licensing terms (when downloading SIP firmware) ?<br>This way we might double check if CCM license is mandatory to connect a Cisco SIP phone to an Asterisk server.<br><br>Beside that, Cisco SIP phones require menu localization files to come from CCM.
<br>Did you run into this ?<br>Is there anything special with these phones that make those localization files to be downloaded (I know that's another topic, but while we're at it ...)<br><br>Regards<br>
