R2000: Make recall work when call is directly answered by call_up_setup
...
It is not recommended to use recall function with built-in MNCC (auto-answer),
because the phone is not fast enough to switch back to call control channel
and so it misses the first paging. But anyway it works.
Also the channel layout is checked for having traffic and control channel.

A-Netz: Number of operator can be defined now

Since A-Netz does not allow automatic dialing, the call is forwarded

Add option to cross-connect calls; Calls between mobiles are now possible
...
Use -x to enable call cross-connect. No MNCC socket, no call device must
be specified!
Be sure to have at least one control channel and two voice channels.
Alternatively you can use one combined control/voice channel and one
voice channel.

...
This way the control channel stays available for other (idle) phones.
No more loss of coverage for other phones, when a call to a mobile is
made.
It is still possible to define a combined control+traffic channel.
(e.g. for single channel setup)

Implementation of RX level squelch (for A-Netz and B-Netz)

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
