Gain 1 

gain in dB 
+3dB to –31dB 
and  “mute” 
setting 

Amplification factor of  lower 
frequency of pair.   
This applies to the dial, ring, busy 
and ‘unobtainable’ tones that the 
MultiVOIP outputs as audio to the 
FXS, FXS, or E&M port. Default:   -
16dB 

Gain 2 

gain in dB 
+3dB to –31dB 
and  “mute” 
setting 

Amplification factor of  higher 
frequency of pair. 
This applies to the dial, ring, busy, 
and ‘unobtainable’ (fast busy) tones 
that the MultiVOIP outputs as 
audio to the FXS, FXO, or E&M 
port.  Default:   -16dB 

Cadence 
(msec) On/Off 

n/n/n/n 
four integer time 
values in  
milli-seconds; 
zero value for 
dial-tone 
indicates 
continuous tone 

On/off pattern of tone durations 
used to denote phone ringing, 
phone busy, connection 
unobtainable (fast busy), dial tone 
(“0” indicates continuous tone), 
survivability, and re-order.  Default 
values differ for different 
countries/regions.  Although most 
cadences have only two parts (an  
“on” duration and an “off” 
duration),  some telephony 
cadences have four parts.  Most 
cadences, then, are expressed as 
two iterations of a two-part 
sequence.  Although this is 
redundant, it is necessary to allow 
for expression of 4-part cadences. 

Custom 
(button) 

-- 

Click on the “Custom” button to 
bring up the Custom Tone Pair 
Settings screen. (The “Custom” 
button is active only when 
“Custom” is selected in the 
Country/Region field.)  This screen 
allows the user to specify tone pair 
attributes that are not found in any 
of the standard national/regional 
telephony toning schemes.
