PSTN Lifeline Application Notes
Usage of PSTN Lifeline
By using the PSTN lifeline function, you can make and receive regular PSTN phone calls in coexistence with
VoIP service on the same set of phone. This can be done by simply assigning a prefix number (by default the
prefix for PSTN dial out is 0000 and can be change to value you wish to) and dial this prefix to switch over to
PSTN line than dial the PSTN number as normal.
Furthermore, when the P2602RL – D3A experience power loss such as in case of earthquake and other natural
hazard that cause power loss, it will automatically switch to PSTN line and you can dial a regular phone number
without dialing a prefix number.
