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
(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 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.
