Configuration option for FXS port ring cadence for all incoming calls. (Syntax: 
c=on1/off1-on2/off2-on3/off3; [...]) 

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.
