GXW400X User Manual
Lifeline Mode
Life line feature ensures user can place/receive a PSTN call in an emergency
situation.
1. If set to Auto”, in case of power loss or loss of SIP registration, the
PSTN line will be seamlessly connected to analog phone connected
to FXS port.
2. If set to Always Connectedthe PSTN line will be always connected
to the phone connected to FXS port. VoIP calls will not be allowed in
this configuration.
3. If set to Always Disconnected, user can only place VoIP calls,
regardless of any power loss and/or SIP registration problems. User
will be unable to place/receive any PSTN calls.
Failover to FXO Gateway
This feature allows users to place an outbound PSTN call in case there is a
loss of an active registration (SIP server unreachable) of all FXS profiles. If
set to “YES”, when GXW400X recognizes a loss of registration, all outgoing
calls will be routed to an FXO gateway.
The use of this option presumes a configured GXW410x or another FXO
gateway with an active PSTN line connection.
FXO Gateway

NTP server

servers can be found at http://www.ntp.org

1440 minutes)
