I'm planning to configure MPX resource as conference bridge in a CCM MRGL with the software conferences of each node in the CCM cluster. CCM CFBs will be sollicited first according to the MRGL. However, CCM CFB does not support G.729 (only G.711) whereas MPX Conf bridge does. I'm wondering, when a caller starts an Ahdoc conference with other users in the same region (using G.711) and at a certain point of time, he adds a user in a diffrent Region configured to use G.729, does the conference drops or the MPX resource is used starting from that moment? If yes, are the CCM bridges used in the same time than the MPX CFB or the CCM bridges are released and MPX CFB is used instead? Does this mean that a conference could be based only on 1 CFB at most?
* A example of a situation where two conference bridges may be used is where a participant in one conference conferences in a participant in a seperate conference.
* Once a conference bridge has the maximum number of participants, additional participants may not be added. No new bridge would be automatically added.
