Specifies whether program will monitor hardware events (so-called DLE codes), and respond to them.

Busy beeps - specifies how many beeps should be detected in order to break the connection
Silence - specifies how long should be the silence in order to break the connection

Specifies whether program will perform Fast Fourier Transform (FFT) analysis on voice data flow.

Busy beeps - specifies beep type the program should monitor.

• simple - detect beeps by their sound level (amplitude modulation)
• single frequency - detect single frequency beeps (default for Europe)
• double frequency - detect double frequency beeps (default for North America)

Disconnect after _ beeps - disconnect the call after specified number of beeps is detected.
