Managing a multicast conference call includes receiving signals at a local endpoint participating in a multicast conference call with remote endpoints. The signals include a local signal associated with the local endpoint and remote signals, where each remote signal is associated with a remote endpoint. Metric ratings are determined, where each metric rating reflects an importance of a signal. The metric ratings include a local metric rating corresponding to the local signal and remote metric ratings, where each remote metric rating corresponds to a remote signal. The local metric rating and the remote metric ratings are compared, and a subset of signals is selected according to the comparison.
