ABSTRACT:
In an example embodiment a method is provided which comprises initiating at an offerer endpoint an offer message in Session Description Protocol (SDP) format. Included in the offer message is an indication of a plurality of potential configurations which the offerer endpoint is capable of supporting. The offer message is sent to an answerer endpoint to allow capability negotiation between the offerer endpoint and the answerer endpoint in a manner that is backwards compatible with existing endpoints. In an example embodiment, the indication of the plurality of potential configurations comprises assigning a new attribute or value to an existing type of SDP identifier.
