Outbound Proxy IP address or Domain name of Outbound Proxy, or Media Gateway, or Session Border

environment supports SIP over the selected transport method. Default is UDP.
NAT Traversal
This parameter defines whether the GXW40XX NAT traversal mechanism is activated or
not. If activated (by choosing "Yes") and a STUN server is also specified, then the
GXW40XX performs according to the STUN client specification. Under this mode, the
embedded STUN client will detect if and what type of firewall/NAT is being used. If the
detected NAT is a Full Cone, Restricted Cone, or a Port-Restricted Cone, the GXW40XX
will use its mapped public IP address and port in all of its SIP and SDP messages.
If the NAT Traversal field is set to "Yes" with no specified STUN server, the GXW40XX
will periodically (every 20 seconds) send a blank UDP packet (with no payload data) to
the SIP server to keep the "hole" on the NAT open.
