Abstract
A system and method for using asymmetric companion codecs to establish and maintain a communication. A communication system endpoint replaces instances of a companion codec with the members of a group of all of the companion codecs for the endpoint and performs appropriate translations of compatible codecs to provide a communication between communication system endpoints.
Claims16
A system for establishing a communication using asymmetric companion codecs, comprising:
- a communication system endpoint that advertises a transmit and receive codec pair in which the system replaces said codec pair, which contains a companion element that is a primary codec, with an expansion using all elements of a companion codec group,
- wherein said companion group is substituted in the place of said primary codec.
A system for establishing a communication using asymmetric companion codecs, comprising:
- a communication system endpoint that advertises a transmit capabilities comprising one or more transmit codecs and receive capabilities comprising one or more receive codecs in which the system replaces a codec pair consisting of a primary codec selected from the transmit codecs and a primary codec selected from the receive codecs with an expansion using all elements of a respective companion codec group of the respective primary codec.
A method for establishing a communication using asymmetric companion codecs, comprising:
- advertising, with a communication system endpoint, a transmit and receive codec pair;
- and
- replacing said codec pair, which contains a companion element that is a primary codec, with an expansion using all elements of a companion codec group,
- wherein said companion group is substituted in the place of said primary codec.
