    • A distributed features system is disclosed which permits a telecommunication network to accommodate the creation of open multimedia services. In accordance with an embodiment of the present invention, protocol extensions for a distributed feature system are disclosed which accommodate a broader range of media choices than conventional telephony. Protocols are disclosed for internal calls between modules in the distributed feature system that permit a module to open and close any number of media channels to be utilized in the communication usage. A protocol is also disclosed for internal calls between modules in the distributed feature system that is more appropriate for a packet-switched reference implementation.
