4.6.3.6 Network Address Translation <nat/>

These parameters define port and IP address changes used in NAT traversal. The port changes will change the port used by the phone, while the IP entry simply changes the IP advertised in the SIP signaling. This allows the use of simple NAT devices that can redirect traffic, but do not allow for port mapping. For example, port 5432 on the NAT device can be sent to port 5432 on an internal device, but not port 1234.

	Permitted
Attribute	Values	Default	Interpretation
nat.ip	dotted-deci-	Null	IP address to advertise within SIP signaling -
	mal IP		should match the external IP address used by
	address		the NAT device.
