Yes, this is exactly how it works, by calling the b2b_init_request on 
the initial Invite, so that B2BUA is in the middle of the call and can 
control it. If you look in the xml scenario file you will see that there 
is a rule for REFER there - this is how it know that when a REFER is 
received it has to do what it has to do.
Try this out  and you will see ;) .
