[OpenSIPS-Users] Provisional response handling in case of forking

[Bogdan-Andrei Iancu]

Hi Agalya,

Inthe onreply_route(), the logic seems ok:
     * if flag set -> drop and log
     * for all 180, set the flag.
This should allow only the first 180 reply to pass.

But I do not understand what is the purpose of the relay2 route? the 
onreply route should go everything you need (in terms of 180 logic).
