SDR: Fix level range of IQ date; must not exceed range of -1 .. 1
...
LimeSDR mini (and maybe others) do not want IQ data to become a value below
-1 or above 1. This happens slightly when applying the IIR filter after
upsampling. To prevent this, we scale down the IQ level a little bit.
To test the problem:
- set the scale level to 1.0, so it does not take effect
- use LimeSDR mini
- use upsampling (sample rate differs SDR sample rate)
- run loopback mode 2 (-l 2)
- IIR filter must be initialized with 2 or more iterations to take effect
- check linear IQ graph; it will then plot dots inside the circle

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.
