This Recommendation addresses interfaces for audio, video and text communications between user equipment (UE), media gateways (MG) and other network elements, such as media servers that process media. Specifically, it identifies the audio and video codecs and other features necessary to provide the highest quality and the most resource-efficient media streams to the customer.
