Maybe you would be better suited to using clear channels. Remove any
telephony signalling from the channels. Then you might be able to go
back to using the /dev/zap/1 method for reading the data. Just remember
that there isn't a buffer so you need to be able to service the channel
quickly or you may lose audio over the link.
