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.

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

Neu structure for the paging process (B-Netz)
...
Paging tones are not created within sound_alsa.c
The audio API is now responsible to switch to paging channel.
In case of SDR, the sdr.c will switch frequency offset.

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.
