Method and apparatus for communication amongst a plurality of endpoints is described. In one example, a logical communication channel is established amongst a plurality of endpoints. The logical communication channel is implemented using at least one physical link of at least one communication network. At least one initial media stream is propagated within the logical channel at a first time. At a second time, at least one media stream is bridged onto, and/or removed from, the logical communication channel without establishing another logical communication channel. In another example, a logical communication channel is established amongst a plurality of endpoints. The logical communication channel is implemented using a first physical link. A first media stream is propagated within the logical channel at a first time. At a second time, the logical communication channel is switched from the first physical link to a second physical link without establishing another logical communication channel.
