[OpenSIPStack] Open SBC Configuration

[<na...@yu...>]

Hi,
 
Open SBC came right up following the build instructions.  The
application is Nat transversal and RTP proxy.  Here is the
configuration:
 
SIP Server  <- ----------------> OSBC <-
-------------------------------> Internet<- -------------------> Router
<- ----------------------> Sip Client
 
PrivateIP A             PrivateIP B and Public IP A
Public IP B and PrivateIP C                  Private IP D
 
 
I have tried changing every field that made sense to me though the OSBC
web interface and so far have only been able to make the Sip Client ring
and have one way voice.
 
What setting on the OSBC need to be changed to make this work?  What
values/syntax need to be used?
 
Thanks,
 
Don
