RE: [Sip] refer-06 question

vsk,

Thanks for the answer.
I understand both cases; but this does not light my way.
Let me put it in other words.

can i delay the notification until the referenced request completes?
leading to send only 1 notification???? (assuming timers are OK).

Or am i oblige to send a 1rst notification, wait for completion of the 
referenced request and send a final notification ?

What is mandatory?

Patrick
