 That's an interesting application. :)

 Since app_parkandannounce is channel technology agnostic, you
wouldn't really be able to grab the SIP hdr itself within the
application because you could have no assurance that it's going to be
there depending on what channel calls the app.

 An alternative might be to use the SIP_HEADER dialplan function to
grab the Refered-By header and then feed that into the dial argument
of the app_parkandannounce app after any massaging of the data
necessary?
