Description 
Disconnect Supervision fields 
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.

Reversal 
Y/N 
Disconnection to be triggered 
by reversal of current from the 
PBX. 
Current Loss 
Y/N

by loss of current.  That is, 
when Current Loss is enabled 
(“Y”), the MultiVOIP will hang 
up the call at a specified 
interval after it detects a loss of 
current initiated by the attached 
device. 
Current Loss 
Timer

(in milliseconds) 
Determines the interval after 
detection of current loss at which 
the call will be disconnected. 
Silence
