<tt>Hi, Royee!<br>
<br>
Can you make sure that fix_nated_contact() is called before
create_dialog()?<br>
Also, if you run through MI the dlg_list_ctx command, what is the
contact header stored in the dialog?<br>
<br>
Best regards,<br>
Răzvan<br>

<div style="color:rgb(33,33,33);font-size:13px">I'm having some
problems when using topology hiding. In my scenario an INVITE
comes in to the opensips (SBC) instance from another opensips
instance (Proxy). It is routed to a callee which eventually
answers with a 200OK. The 200 OK is routed through the SBC to
the Proxy which answers back with an ACK. This ACK is absorbed
by the SBC which (by looking at the logs) attempts to send
this ACK to the private IP of the callee instead of the the
NAT IP which was originally used for the incoming INVITE.</div>
