[OpenSIPS-Users] B2B: how to-header is formed?

[Nick Altmann]

Core team, what do you think about it?
I can do patch, but I'd like to discuss method to change b2b options.

The first option is to enable/disable transparent authentication.
The second options is to enable/disable from header mangling.

I think it should be flag to b2b_init_request command or separate
command to change options.
