A communication service is provided that enables end-users to interactive ly communicate over a communication channel using individually selected comm unication interfaces at each end-point of the channel. Each end-user may sel ect a receive interface that presents communications to the end-user in a fo rmat that is most desirable to the end-user. As a result, an end-user is no longer subjected to the interface selected by an initiator of a communicatio n. The communication service may be used to allow users of instant messaging (IM) services to seamlessly communicate with users of voice services such a s Push-to-Talk-over-Cellular (PoC) services.
