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 IP Address or URI of the FXO gateway.
NTP server 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
at http://www.ntp.org
NTP Update Interval Default is 1440. Updates the Network Time Protocol (Values range from 5 – 1440
minutes)
Syslog Server The IP address or URL of System log server. The server collects system log
information from the device.
Syslog Level Select the GXW400X to report the log level. Default is NONE. The level is one of
DEBUG, INFO, WARNING or ERROR. Syslog messages are sent based on the
following events:
1. product model/version on boot up (INFO level)
2. NAT related info (INFO level)
3. sent or received SIP message (DEBUG level)
4. SIP message summary (INFO level)
5. inbound and outbound calls (INFO level)
6. registration status change (INFO level)
7. negotiated codec (INFO level)
8. Ethernet link up (INFO level)

The Syslog uses USER facility. In addition to standard Syslog payload, it contains
the following components:
GS_LOG: [device MAC address][error code] error message
Example: May 19 02:40:38 192.168.1.14 GS_LOG: [00:0b:82:00:a1:be][000]
Ethernet link is up
Send SIP Log If Syslog is enabled and Send SIP Log is set to YES, then SIP messages will also be
delivered via Syslog. Default is set to NO.
