Only when busy, the channel has callref. This is required for audio
routing. During setup, the callref assigned to transaction and kept
there until release to/from upper layer.

C-Netz: Calibration/fix processing of tone levels on TX and RX side
...
FSK and compander levels are adjusted.
Eliminate offsets between subsequent speech chunks. This is done by
high-pass filter. An offset is not passed to the filter.
Do correct audio processing chain:
time compress -> compressor -> scrambler / pre-emphasis -> TX
RX -> de-scrambler / de-emphasis -> expander -> time expand
