Hello,

The fact you are changing the interface (actually your are bridging networks) have nothing to do neither with TO and FROM hdrs (they contain callee/caller identities, nothing to do with routing), nor with the Contact hdr (this contains the IP coordinates of the sender of the package, not to be changed in this case).

In a interface changing scenario, the things that change are the VIA and RR headers added by the proxy doing the changing. This can be done by opensips automatically (see the mhomed) or manually (via the force_send_socket). See:

Hello all,
I am trying to setup a opensips server that has 2 ip's one internal and one external IP. I have set the rewritehostport to an external IP. When I send the call to the internal NICs IP the invite makes it to the external server but my to: from: and header contact all show the original IPs and the header contact is the internal NICs IP.

Should I be able to configure the open sips server to branch a new call that shows the call originating from the external NIC IP of the opensips server? I have setup rtpproxy that is working fine changing the SDP contact and media ports to the external NIC's IP. Can anyone point me in the correct direction?

Thanks,

James
