SIP NAT Bridge Configuration

You create a bridge between SIP NATs by pointing them at one another. You point the SIP NATs at each other by configuring the home address and home proxy address to create the bridge. In addition, you can configure the route home proxy on the customer’s side of a SIP NAT to force all requests to be routed to the corresponding backbone SIP NAT, regardless of the Request URI. You need to force requests when elements in the customer’s network send requests with a Request URI that does not match the customer’s SIP NAT external address. Or when the Request URI does not match a local policy element that would route the requests to the backbone SIP NAT.

You also need a home network to create a SIP NAT bridge. If you do not have a real home network, you need to create a virtual one. You also need to configure instances of the SIP NAT to create the SIP NAT bridge within your network.
