Configuration option for FXS port ring cadence for all incoming calls. (Syntax:
c=on1/off1-on2/off2-on3/off3; )
Note : Maximum supported cadences is 3
Using these settings, users can configure tone frequencies according to their
preference. By default they are set to North American frequencies.
These tones 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.
Example for North America Dial Plan:
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)
