Abstract

Endpoints, such as clients and gateways, maintain local codec priority lists (500), receive remote codes priority lists (504), and maintain common communication attribute priority lists (502). When opening a transmittal channel, a local endpoint determines the highest priority codec on its local priority list (500) that is also on the remote priority list (504). The local endpoint also determines the highest priority codec on the remote priority list (504) that is also on the local priority list (500). If the codes types match, then the transmitting channel is opened with that codec. If there is no match, then the common communication attribute priority list (502) is used, and the local or remote codec that has a corresponding highest or lowest desired attribute is used for the communication.
