Abstract
Techniques are provided herein to add multicast media streams to teleconferencing sessions without the unwanted side effects that occur when a speaker's own media is echoed back to the speaker. Multicast and unicast media streams are generated by a network device, e.g., a conference bridge, and distributed to any number of endpoints, e.g., conference endpoints. A media selector is provided that selects the appropriate multicast or unicast media stream for forwarding to an associated network endpoint.
