Level adjustment:
We see a receive level of around 140%.
Then start the base station using '-L 2' option for loop-back and tune receiver to the transmitter.
Then start the base station using '-l 2' option for loop-back and tune receiver to the transmitter.
The base station generates a 1750 Hz test signal, just like the mobile phone.
Use the variable resistor (connecting your transmitter) to adjust the volume until the received level matches the same level of your previously received signal.
In my case I adjust the transmitter to match around 140%. (+- 10% is good)

We do not have any RSSI (Received Signal Strength Indicator) signal from our radio, so we cannot directly find out if the signal is lost.
But we have a constant noise level when the signal is lost.

Whenever the noise level is above the given percentage, loss of carrier is assumed, if the noise level is constant.

After a system specific duration of signal loss, the call is released.
