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.
