1. A method for signaling multiple audio mixing gains in a teleconference using a Real-time Transport Protocol (RTP) header extension, performed by at least one processor and comprising:
receiving mixing gain levels of different audio streams each from a same conference room, the mixing gain levels comprising a first mixing gain level, of a first audio stream of the different audio streams from the same conference room, and a second mixing gain level of a second audio stream of the different audio streams from the same conference room;
declaring a single RTP header extension comprising one or more of an element identifier, a length of an extension element, the first mixing gain level, and the second mixing gain level; and
signaling both the first mixing gain level and the second mixing gain level together in the single RTP header extension,
wherein the first mixing gain level is different than the second mixing gain level, and the single RTP header extension consists of any of a one-byte header extension and a two-byte header extension.
