PROFILE PAGE DEFINITIONS
Setting Options
Meaning
Account Active
When set to Yes the SIP Profile is activated.
SIP Server
SIP Server
‟s IP address or Domain name provided by
VoIP service provider.
Outbound Proxy
IP address or Domain name of Outbound Proxy, or Media
Gateway, or Session Border Controller. Used by SIP
60X for firewall or NAT penetration in different network
environments.
If symmetric NAT is detected, STUN will not work and
ONLY outbound proxy can correct the problem.
NAT Traversal
This parameter defines whether the SIP 60X NAT
traversal mechanism is activated or not. If activated (by
choosing
“Yes”) and a STUN server is also specified, then
the SIP 60X 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 SIP 60X 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 SIP 60X 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.
