SBCE SIP Registration

SBCE SIP Registration

SBCE SIP Registration

(OP)
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?

RE: SBCE SIP Registration

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
