8d7c7f4425 callref: Move callref from 'sender' to individual implementation of a, b, c-netz 
Cellular networks use transaction instances, so callref is now member of
transaction object.

ce7a98206a C-Netz: Move callref to transaction. Callref on SpK only when its busy. 
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.

46fa72894e 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
