I have installed MeetingPlace Express 1.1.2. When I set up the IP phone service on Callmanager to be able to join the meeting through your IP phone, I am able to see all meetings, when I hit the 'Join' button the system says it is calling my phone, but the phone never rings. I have checked my CSS's and Partitions. The error I receive in MeetingPlace logs is Error 5283. Any help would be greatly appreciated.
