Abstract
Methods and systems provide data transmission through unused transmission channels. In one embodiment, the method includes identifying one or more available audio channels in the communication stream available to transmit non-audio data, wherein the communication stream includes a plurality of audio channels and transmitting the non-audio data through the identified one or more available audio channels. Identifying the available audio channels includes determining each audio channels from the plurality of audio channels that is unused in the communication stream. Identifying the available audio channels may also or alternatively include identifying one or more channels from the plurality of audio channels in the communication stream as potential channels available to transmit the non-audio data and reserving the potential channels for transmitting the non-audio data.
