A system and method are disclosed herein for managing conference bridge communication sessions. The system and method involves receiving a plurality of calls containing user media from users into a conference bridge, then connecting the plurality of calls via a load balancer to a plurality of conference servers on a network. A master broker dynamically selects a master conference server from among the plurality of conference servers to which the calls are connected. Once the master conference server is selected, the master broker directs all other conference servers to bridge the user media for the calls that are connected to the master conference server. The master conference server receives the user media from each of the connected conference servers. The master conference server is able to organize and mix the various user media and return this mixed media to each of the connected conference servers and thereby back to each user.
