“Regional Parameter” Definitions
Field Name Values Description
Country/Region
USA,
Japan, UK,
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), survivability tone (tone heard briefly, 2
seconds, after going off hook denoting survivable mode of VOIP unit), re-order tone (a tone
pattern indicating the need for the user to hang up the phone), and intercept tone (a tone
that warns an a party that has gone off hook but has not begun dialing, within a prescribed
time, that an automatic emergency or attendant number is called; the automatic call can be
used to direct an attendant’s attention to a disabled or distressed caller, allowing an
appropriate response to be made).
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.
Note 1: Intercept tone is applicable only when the FXS telephony interface has been chosen
in the Interface screen and when the AutoCall / OffHook Alert field is set to OffHook Alert in
the Voice/Fax Parameters screen. The time allowed for dialing before the automatic calling
process begins is set in the OffHook Alert Timer field of the Voice/Fax Parameters screen.
Note 2:
“Survivability” tone indicates a special type of call-routing redundancy and applies
to MultiVantage VOIP units only

Type of telephony tone-pair for which frequency, gain, and cadence are being
presented.
Frequency 1 freq. in Hertz Lower frequency of pair.
Frequency 2 freq. in Hertz Higher frequency of pair.
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

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