SBCE SIP Registration

[cfickes]

Currently the carrier gets the invite from our public address, and they are responding with a 401 but they say we need to check the NAT so it is not masking the contact and via headers in the register.

In the registration (contact/via) below it is sending the B1 interface IP instead of the public IP. How can this be modified?

usually in the network config of the sbc where you define the B1 IP/gateway there's a field for public IP it should be using just like how IPO has one on the LAN1 tab
