Abstract
A system includes the ability to establish a communication session between stations using protocol capabilities of an external transcoder. The stations may establish a communication session by exchanging protocol capabilities which include a protocol capability of at least one remotely located transcoder. The communication session may then be established using appropriate signalling protocol, including peer-to-peer signalling protocols.
