[OpenSIPS-Users] B2BUA & Proxy Interaction

[Bogdan-Andrei Iancu]

Hi Ben,

You can use the local route to do routing on the outgoing requests - 
like doing drouting, or usrloc lookups. But in B2B mode, some signaling 
related functionalities, like dialog support, accounting support will 
not work (because you do not have a proxy transaction, but only a UAC 
one) - of course, you can do manual ACC (directly from via script 
functions)..
