It looks something like this (grossly simplified)

[PC]---[ASYNC bitstream]----[Compressor]---[Reliable Link Protocol]--(1)

(1)----[Synchronous Bitstream]-------[Codecs]-------->telephone

So the bit rate is constant across the phone line. The reliable link protocol
is needed to make the streaming compression work sensibly.
