Configuration option is set ring cadence on FXS port for all incoming calls.
Syntax: c=on1/off1-on2/off2-on3/off3; (3 cadences maximum)
Default is set to c=2000/4000; (US standards)
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.
Dial tone:
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)
