[OpenSIPS-Users] avp scope bug in 3.2 ?

[Răzvan Crainea]

Hi, Johan!

This is the intended behavior.
Local route is run for requests generated by OpenSIPS. I can't see in 
your snippet where you call route(relay) from, but if it's not from 
local route, it must be from a different route that is executed for 
received messages (rather than generated ones), thus completely 
different requests.
If you are looking for a B2B scope variable, you should be looking at 
the new #b2b_logic.ctx var[1].
