It does. The only place this is implemented is in asterisk itself
(ie none of the client libraries implement it - though it wouldn't be
that hard to add).
Asterisk demultiplexes the audio in chan_iax2, so it's almost completely
hidden. The only clue that 2 audio streams arrived in the same IAX trunk
would be in the timing (and possibly the channel name).
