[OpenSIPS-Users] Drouting problem

[Bogdan-Andrei Iancu]

Hi Brett,

:D oh...I'm wrong - i forgot that DR accepts only avps and not generic 
PVs ; when a generic PV is evaluated, you can use transformations (as 
they will be used), but in this particular case (only AVPs), the 
transformation will not be automatically applied :(.

So, you are right, here the correct way to do it is via an intermediary 
INT AVP.

Regards,
Bogdan
