FXO Lifeline Application Notes
This FXO Lifeline application notes section is for P-2812HNUL-Fx only. Here we use
P-2812HNUL-F1 as example
Usage of FXO Lifeline
By using the FXO lifeline function, you can make and receive regular FXO phone calls
in coexistence with the VoIP service on the same phone set. This can be done by
simply assigning a prefix number (by default the prefix for FXO dial out is 0000 and
can be changed to any desired value) and dialing this prefix to switch over to the FXO
line, rather than dialing the FXO number as usual.
Furthermore, when the P-2812HNUL-Fx experiences power loss such as in the case
of earthquake and other natural hazard that causes power loss, it will automatically
switch to the FXO line and allow you to dial a regular phone number without dialing
the prefix number.
This can be applied in emergency situations such as for contacting police, fire or
emergency medical services during a power outage. The following section illustrates
how to configure the lifeline in P-2812HNUL-Fx Web GUI.
