[OpenSIPS-Users] b2b_init_request('top hiding')

[Anca Vamanu]

Hi Dani,

As Ovidiu said - b2b doesn't work with nat_traversal. The main 
limitation comes from the fact that nat_traversal uses dialog module and 
b2b does not work with dialog module yet. The reason is that dialog 
module was designed to store proxied dialog, not the ones where opensips 
is an endpoint.
Indeed there isn't a clear note in documentation about this limitation - 
I will add it now.

Regards,
