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
Ex. May 19 02:40:38 192.168.1.14 GS_LOG: [00:0b:82:00:a1:be][000] Ethernet link is
up
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.
This is a special feature that enables the user to create a text file backup of your
existing configuration.

TABLE 10: FXS PORT SETTINGS

When set to yes the FXS port is activated.
This field contains the URL string or the IP address (and port, if different from 5060) of
the SIP proxy server. e.g., the following are some valid examples: sip.my-voip-
provider.com, or sip:my-company-sip-server.com, or 192.168.1.200:5066
This Field contains the URL or the IP address of a second SIP server, this one will be
used in case the device loses the connection with the first server.
IP address or Domain name of Outbound Proxy, or Media Gateway, or Session Border
Controller. Used by ATA for firewall or NAT penetration in different network environment.
If symmetric NAT is detected, STUN will not work and ONLY Outbound Proxy will work.
User can select UDP or TCP or TLS.
This setting decides whether the NAT traversal mechanism is activated. It should be set
to "Yes" if the device is behind a NAT router. If no outbound proxy is configured, a
STUN server needs to be set to activate STUN detection mechanism. Usually ITSP will
provide these settings. If this field is set to "Yes", then the device will periodically send
a dummy UDP packet to the SIP server to pinhole the NAT.
User account information, provided by VoIP service provider (ITSP), usually has the
form of digit similar to phone number or actually a phone number. This field contains
the user part of the SIP address for this phone. e.g., if the SIP address is
sip:my_user_id@my_provider.com, then the SIP User ID is: my_user_id.
Do NOT include the preceding "sip:" scheme or the host portion of the SIP address in
