Every call bridged though a specific 'gateway' does rewrite the SIP request URI domain and To URI domain values to the gateway's 'proxy' parameter value.

I would like to respect such values and receive in my proxy the SIP messages with their original request URI domain and To URI domain. 

This is, I would like to be able to send a SIP message with the following request URI and To headers, to the IP address 2.2.2.2

```

INVITE sip:jmillan@1.2.3.4 SIP/2.0 Via: SIP/2.0/TCP bl23sl8lmku7.invalid;branch=z9hG4bK9420964 To: <sip:d@1.2.3.4>```

```

Is it possible to handle this with FreeSwitch?

I have followed the FS wiki but I've been unable to handle this.

Thanks in advance.
