For completeness,
the BYE is part of the dialog established by the INVITE transaction that
ended when "200 OK" was received. But the BYE itself starts another
transaction.
So, the AVPs you set in the processing of the INVITE will be available (as
long as you use module tm) when your process responses for that INVITE (180,
183, 200 etc), but not when you are handling other requests in the dialog.
