Custom
Name of a country or region that uses a certain set of tone pairs for
dial tone, ring tone, busy tone, unobtainable tone (fast busy tone), and
re-order tone (a tone pattern indicating the need for the user to hang
up the phone).
In some cases, the tone-pair scheme denoted by a country name may
also be used outside of that country. The “Custom” option (button)
assures that any tone-pairing scheme worldwide can be
accommodated.

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.
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 or FX0 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 or FXO port.
Default: -16dB
