Call Progress Tones Using these settings, users can configure tone frequencies and cadence according
to their preference. By default they are set to North American frequencies.
Configure these settings with known values to avoid uncomfortable high pitch
sounds. ON is the period of ringing ("On time" in 'ms') while OFF is the period of
silence. In order to set a continuous tone, OFF should be zero. Otherwise it will
ring ON ms and a pause of OFF ms and then repeat the pattern.
Example configuration for N.A. Dialtone:
f1=350@-13,f2=440@-13,c=0/0;
Syntax: f1=freq@vol, f2=freq@vol, c=on1/off1-on2/off2-on3/off3; [...]
(Note: freq: 0 - 4000Hz; vol: -30 - 0dBm)
