One-to-One Configuration

In the one-to-one scenario, a single customer SIP NAT is tied to a single backbone SIP NAT. The home proxy address field value of the backbone SIP NAT must match the home address of the customer SIP NAT. On the customer side, the home address of the customer SIP NAT should be defined as the home address of the customer, the home proxy address field value should match the home address of the backbone SIP NAT, and route home proxy should be set to forced.

The following table lists the field values you need to set to create a one-to-one SIP NAT bridge.

SIP NAT Entity	Field	Sample Values
Backbone SIP NAT	home address	IPv4 address of the home realm. For example: 127.0.0.110
	home proxy address	IPv4 address of the home proxy from the perspective of the external realm. 127.0.0.120
Customer SIP NAT	home address	127.0.0.120
	home proxy address	127.0.0.110
	route home proxy	forced
