aeb31a7a34 A-Netz: Number of operator can be defined now 
Since A-Netz does not allow automatic dialing, the call is forwarded
to an operator. Use -O <number> to change the default operator's number.

b32e0ab602 Implementation of RX level squelch (for A-Netz and B-Netz) 
Use -S <dB> for setting RF level or use -S auto for auto level.

When squelch closes, audio is muted. If squelch is closed for some
seconds (depending on network), call is released. (RF loss condition)

The previous loss detection has been removed

52b1ac65f4 A-Netz: Keep phase for each paging tone when played in sequence 
If paging tones are played in sequence, only one tone out of four tones
is played at once. The phase of all tones are calculated as if each tone
would have been sent permanently.

4356c93afa common: Add pre and de emphasis, if the radio does not support it 
Connect to the oscillator of the transmitter - good girl!
You need to enable pre emphasis in this case.

Connect to the discriminator of the receiver - good boy!
You need to enable de emphasis in this case.

1146537d84 common code: Add feature to record received audio and replay it 
-W <file.wav> writes a wave file of received audio
-R <file.wav> reads a wave file to feed into decoder

This way you can record a phone and later debug without a phone
and radio equipment.
