Description
Country Selection for
Built-In Modem
(not applicable to
MVP210)
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.

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.
