System Ring Cadence 
Configuration option is set ring cadence on all FXS ports for all incoming calls. (Syntax:

(US standards) 
Call Progress Tones 
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. Dialtone: 
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)
