System Manual
Lifeline Port
What’s this?
• Some times even if there is IP Network problem dialing of important
number is required. For this the Gateway supports to dial such
numbers from PSTN line connected to a port known as ‘Life Line
port’. It is not a true FXO port and IC calls are not supported.
• This feature is useful in following conditions:
• If the Ethernet link is down.
• If the SIP account fails to get registered.
• If an emergency number is to be dialed.
• If you want to dial a number using PSTN.
• If you are unable to achieve toll quality speech through IP due to
some reasons.
• The Gateway will switch back to Normal mode on completion of the
call through Life line port.
• Refer chapter ‘Emergency Number Dialing’ for using Lifeline port.
How it works?
• The system compares the dialed number string with the numbers in
the Access Code Table and if a perfect match is found it connects
the user to the PSTN (Lifeline port).
• The user will listen to the PSTN dial tone and will get prompted to
dial the number again.
• When user dials the number, same will be dialed out by the system.
Important Point:
• This port can be accessed only, from FXS1 port.
