[OpenSIPS-Users] B2BUA & Proxy Interaction

[Bogdan-Andrei Iancu]

Hi Ben,

In 1.11, usage of t_on_failure (and of a failure route) froma local 
route is possible. Give it a try, it should work :).

In regards to the B2B replication - there is not yet on the map (at 
least not for 2.1) . It will be consideredafter doing some refurbishing 
of the B2B module.

Best regards,
