ABSTRACT:
A communication system in which a profile of codecs is loaded at the originating end. The originating end sends the profile of codecs to the terminating end and receives in return an indication of which codec to use. The originating end and the terminating end create a reduced profile that includes the codec identified by the terminating side and it's peers. The peers are codecs that use the same amount of resources as the selected codec or that use less resources than the selected codec. Even though the reduced profile includes more than one codec, packets are coded and decoded using only the codec identified by a bit map that is available to the DSP channel at both the originating end and the terminating end. At a later time a change can be made to a different codec in the reduced profile by changing the bitmap and without closing and re-opening the channel.
