Jeffrey Ness | I believe HTTPS support was added (from a CUCM side) in 8.0 and higher (in CUCM there are separate HTTP and HTTPS URLs in Enterprise Parameters and IP Phone Service definitions if it is supported.) This is also dependent on IP Phone Firmware. I have implemented several HTTPS phone services in 8.5 and there are some caveats: 1) the web server public certificate (not private) needs to be added to CUCM servers on the OS side as a phone-CTL-trust. If using not using security between CUCM and phones (e.g. you have never obtained/used the security tokens and have never run the CTL wizard) this is sufficient; otherwise you need to (re)run the CTL wizard. 2) As of 9.1(1) there was a bug in using port 443 (explicitly or just as https) and just using another port works (see bug IDs CSCtj62147). Also on 8.5 there is a bug (CSCtr78976) that resets Enterprise Parameter Secure URLs upon restart. |
