environment supports SIP over the selected transport method. Default is UDP.

This parameter defines whether the GXW42XX NAT traversal mechanism is activated or not.
If activated (by choosing “Yes”) and a STUN server is also specified, then the GXW42XX
performs according to the STUN client specification. Under this mode, the embedded STUN
client will detect if and wha
t type of firewall/NAT is being used. If the detected NAT is a Full
Cone, Restricted Cone, or a Port-Restricted Cone, the GXW42XX
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 GXW42XX
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.

-A Record (for resolving IP Address of target according to domain name)
