I have users that are getting busy signal when Dialing into Meetme Conf. I think I am hitting a limit on users, becasue some get in fine. How do I see how many users can join the conf and how many are in use during a conf.? I had a vendor help me set this up initially and I want to understand how this works better.
Are you using the MeetMe feature on CallManager ? If so, the initiator of the MeetMe conference needs to select the 'MeetMe' softkey and then dial the meetme number. All other users directly dial into the meetme number (no meetme softkey)
You can look into the Cisco CallManager service parameter 'Maximum MeetMe Conference Unicast' and increase it, if needed.
Keep in mind that the initiator can't be an outside caller when trying to use the CallManager MeetMe feature.
