This parameter defines whether the HandyTone ATA NAT traversal
mechanism will be activated or not. If activated (by choosing "Yes") and a
STUN server is also specified, then the HandyTone ATA will behave according
to the STUN client specification. Under this mode, the embedded STUN client
inside the HandyTone ATA will attempt to detect if and what type of
firewall/NAT it is sitting behind through communication with the specified
STUN server. If the detected NAT is a Full Cone, Restricted Cone, or a Port-
Restricted Cone, the HandyTone ATA will attempt to use its mapped public IP
address and port in all its SIP and SDP messages. If the NAT Traversal field is
set to "Yes" with no specified STUN server, the HandyTone ATA will
periodically (every 20 seconds or so) send a blank UDP packet (with no
payload data) to the SIP server to keep the "hole" on the NAT open.
This parameter specifies how often the HandyTone ATA sends a blank UDP
packet to the SIP server in order to keep the "hole" on the NAT open.
NAT IP address is used in SIP/SDP message. Default is blank.

depending on network environment. Do not interrupt the firmware upgrading
