Description
Country Selection
for Built-In Modem
(not applicable to
MVP130 or 130-
FXS)
country name
MultiVOIP units operating with the X.06 software release (and above) include a
built-in modem. The administrator can dial into this modem to configure the
MultiVOIP unit remotely. The country name values in this field set telephony
parameters that allow the modem to work in the listed country. This value may be
different than the Country/Region value. For example, a user may need to choose
“Europe” as the Country/Region value but “Denmark” as the Country-Selection-
for-Built-In-Modem value.
User Defined Tones fields
Type column
alphanumeric
name
Name of supervisory tone pair. Cannot be same as name of any standard tone pair.
Frequency 1
Freq. in Hertz
Lower frequency of pair.
Frequency 2
Freq. in Hertz
Higher frequency of pair.
Gain 1
+3dB to –31dB
and “mute” setting
Amplification factor of lower frequency of pair.
This applies to any supervisory tones that the MultiVOIP outputs as audio to the
FXS or FXS port. Default: “Mute”
Gain 2
+3dB to –31dB
and “mute” setting
Amplification factor of higher frequency of pair.
This applies to any supervisory tones that the MultiVOIP outputs as audio to the
FXS or FXO port. Default: “Mute”
Cadence
(ms) On/Off
n/n/n/n
four integer time
values in
milliseconds; (zero
value indicates
continuous tone)
On/off pattern of tone durations used to denote supervisory tones specified by
user. Supervisory tones relate to answering and disconnection of calls. 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.
Setting Custom Tones and Cadences (optional)
The Regional Parameters dialog box has a secondary dialog box that allows you to customize DTMF tone pairs to
create unique ring-tones, dial-tones, busy-tones or “unobtainable” tones or “re-order” tones or “survivability”
tones for your system. This screen allows the user to specify tone-pair attributes that are not found in any of the
standard national/regional telephony toning schemes. To access this customization feature, click on the Custom
button on the Regional Parameters screen. The “Custom” button is active only when “Custom” is selected in the
Country/Region field.

Tone Pair
dial tone, busy tone

tone, survivability tone,
re-order tone
Identifies the type of telephony signaling tone for which frequencies are being
specified.
Tone Pair Values
About Defaults: US telephony values are used as defaults on this screen.
Frequency 1
Frequency in Hertz
Frequency of lower tone of pair.
This outbound tone pair enters the MultiVOIP at the input port.
Frequency 2
Frequency in Hertz
Frequency of higher tone of pair.
This outbound tone pair enters the MultiVOIP at the input port.
Gain 1
+3dB to –31dB
and “mute” setting
Amplification factor of lower frequency of pair. This figure describes amplification
that the MultiVOIP applies to outbound tones entering the MultiVOIP at the input
port. Default: -16dB
Gain 2
+3dB to –31dB
and “mute” setting
Amplification factor of higher frequency of pair. This figure describes
amplification that the MultiVOIP applies to outbound tones entering the
MultiVOIP at the input port. Default: -16dB
Cadence 1
integer time value in
milliseconds; zero value
On/off pattern of tone durations used to denote phone ringing, phone busy, dial
tone (“0” indicates continuous tone) survivability and re-order. Cadence 1 is
