Abstract
A computer-implemented method includes receiving registration messages at a call control agent device via first unicast transmissions from at least three video conference terminals. The registration messages request set up of a video conference between the at least three video conference terminals. The computer-implemented method includes sending a set up message from the call control agent device to each of the at least three conference terminals via second unicast transmissions. The set up message includes at least an identification of a multicast control group, a send multicast group of each of the at least three conference terminals, and a default receive multicast group. In response to the set up message, one or more of the at least three video conference terminals join the default receive multicast group.
