Call Progress Tones 
Using these settings, users can configure ring or tone frequencies based on 
parameters from local telecom. By default, they are set to North American standard. 
Frequencies should be configured with known values to avoid uncomfortable high 
pitch sounds. 
Syntax: f1=val,f2=val[,c=on1/off1[-on2/off2[-on3/off3]]]; 
(Frequencies are in Hz and cadence on and off are in 10ms) 
ON is the period of ringing (“On time” in ‘ms’) while OFF is the period of silence. In 
order to set a continuous ring, OFF should be zero. Otherwise it will ring ON ms and a 
pause of OFF ms and then repeat the pattern. Up to three cadences are supported.
