ABSTRACT:
Conferencing nodes transmit messages back and forth to negotiate characteristics for their conferencing session. The messages identify different sets of conferencing capabilities supported by the conferencing nodes. A first node transmits a request to a second node, wherein the request identifies a first set of conferencing capabilities of the first node. The second node transmits a response to the first node, wherein the response identifies a second set of conferencing capabilities of the second node and the second set is a subset of the first set. The first node and second node conduct conferencing based on the second set.
