Abstract

Managing a multicast conference call includes receiving signals at a local endpoint (20) participating in a multicast conference call with remote endpoints (20). The signals include a local signal (30) associated with the local endpoint (20) and remote signals (32), where each remote signal (32) is associated with a remote endpoint (20). 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 (30) and remote metric ratings, where each remote metric rating corresponds to a remote signal (32). The local metric rating and the remote metric ratings are compared, and a subset of signals is selected according to the comparison.
