country name
TalkAnytime units include a built-in modem. The administrator can dial into this
modem to configure the TalkAnytime 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.

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.
