TABLE 10: FXS PORT SETTINGS
Account Active When set to yes the FXS port is activated.
SIP Server 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
Failover SIP Server 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.
Outbound Proxy
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.
SIP Transport User can select UDP or TCP or TLS.
NAT Traversal (STUN) 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.
