connection notice to the calling party only when the Answer Delay
Timer expires. The connection notice is sent regardless of whether
or not the called extension has gone offhook.

Description
There are four possible criteria for disconnection under FXO:
current reversal, current loss, tone detection, and silence detection.
Disconnection can be triggered by more than one of the three
criteria.
Y/N
Disconnection to be triggered by reversal of current from the PBX.
Y/N
Disconnection to be triggered by loss of current. That is, when
Current Loss is enabled ("Y"), the TalkAnytime will hang up the
call at a specified interval after it detects a loss of current initiated
by the attached device.
200 to 2000
Determines the interval after detection of current loss at which the call
(in milliseconds)
will be disconnected.
Y/N
Enables/disables silence-detection method of supervising call
disconnection.
One-Way or
Disconnection to be triggered by silence in one direction only or in
Two-Way
both directions simultaneously.
integer value
