[OpenSIPS-Users] B2BUA tests

[Anca Vamanu]

Hi Jeff,

I have completed the documentation on 
http://www.opensips.org/Resources/B2buaTutorial#toc12 with some schema.
What happens in topology hiding is that the B2BUA starts a new dialog 
with the other party, so it will first send an INVITE message. Now, if 
you call b2b_init before you do lookup location and the target address 
is has in the domain part the domain of your sip proxy, then the INVITE 
will get back to the server and back in the script. For this case I was 
saying that you should not require authentication for it.
And no, the B2BUA component does not have any type of authentication of 
its own, it only knows to put itself in the middle of the call and 
establish two dialogs, with each party.

Regards,
Anca
