Table 5-5 Description of SIP General Settings
STUN (Simple Traversal of UDP through NATs) is a protocol for assisting
devices behind a NAT firewall or router with their packet routing.
The STUN server allows clients to find out their public address, the type of
NAT they are behind and the internet side port associated by the NAT with
a particular local port. This information is used to set up UDP
communication between the client and the VOIP provider and so establish
a call.
The IP address that will be associated with outbound SIP messages if the
system is in a NAT environment.
Alternatively you can specify an external host, and the system will perform
DNS queries periodically.
This setting is only required when your public IP address is not static. It is
recommended that a static public IP address is used with this system.
Please contact your ISP for more information.
