Call Progress Tones
Using these settings, user can configure tone frequencies according to their preference. By default
they are set to North American frequencies.
Frequencies should be configured 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.
