Today I read the RFC and had the same impresion :)

Ok, I'm going to try it out.  One question, this means that I _need_ to 
use t_relay() to send the request to the IVR? ... I need it to be 
scalable so I think if I can use forward() and disable record routing it 
would scale better (I don't know if as much as with redirects).

Thanks for you answers.
