[OpenSER-Users] scope of openser flags

[Bogdan-Andrei Iancu]

Hi Hugo,

The flags you mention are per transaction flags and they are visible as 
time the route is in a transaction context. Unfortunately you came 
across the only exception. You are using the generic "onreply_route" 
where there is no transaction contect (openser has no idea -yet- about 
the transaction the reply belongs to). A reply route with transaction 
context is onreply_route[x] - this is set per transaction by t_on_reply().

Regards,
Bogdan
