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

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

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.
