Hi,

No, there is no way to do one side topology hiding right now.

What you can do is to use dialog module (with topology_hiding()) and copy (for requests from UAC to proxy) the contact info (that will be hidden by opensips) in a non standard header (like X-Contact), to that proxy will see the original contact from UAC.

Hello all!

I wonder can I make Opensips to hide one side (public) from the inside
(private) at the same time I want inside servers to have information about
UAs on the public? Some sort of topology hiding on one side.

UACs(public)<->  (public)Opensips(private)<->  SIPproxy(Registrar,pstn
gw,...)

1) SIPproxy must see end UACs CONTACT field
2) Opensips must hide all the private staff (RECORD-ROUTES, VIA,... ), so
that UACs see like if they talk only to Opensips.

As far as I could understand Dialog topology_hiding() and B2BUA module, I
can't make that scenario with those commands? I need to manually "fix"
headers with private info?

Any thoughts?
Thanks!
