[OpenSIPS-Users] B2B Top Hiding & Refer

[Bogdan-Andrei Iancu]

Hi David,

Once you put a call through B2B, topology hiding is done - that's the 
nature of a B2B. So simply using the B2B module gives you TH. The TH 
scenario is for case when you want B2B without any scenario , but only 
passing through.

So just use your "refer" scenario and you will see that TH is done for 
the calls.
