Disabling default L7 NAT behavior in the SBC for the core side only

 

 

Hi everyone

 

Hope you all are doing well.

 

I'd like to know if there's a way of disbling the default topology hiding behavior once the realm bridging has taken place.

 

I intend to pass to the core (not the other way around) the original addressing (of the sip devices interacting with the sbc) in order to take action based on those IPs.

 

What I'd like to see is the original IP addressing (at least the addressing that arrives to the sbc in it's public interface with no address translation) for the sip headers.

 

Is there a better way than an inbound HMR that stores the remote ip and pastes it in the relevant headers (from, via, contact...etc) ?
