ratox?

call_in        Initiate a call by piping data to this FIFO.

call_out       Answer an incoming call by opening it for reading.

call_state     Reports the call state (none | pending | active). The sample
format is mono signed 16-bit little endian at 48kHz.  The call is terminated if
ratox receives both an EPIPE trying to read from call_in and ENXIO trying to
open call_out for writing.
