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 Connected" the 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.
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 GXW40XX 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.
IP Address or URI of the FXO gateway.
URI or IP address of the NTP (Network Time Protocol) server. Used by the phone to
synchronize the date and time. An extensive list of public NTP servers can be found
