No.  You need to use ParkAndAnnounce and a feature I'd managed to get added 
which lets you get the parking slot number in the dialplan variable 
${PARKEDAT}.

I use it like this:

exten => _X.,1,...
exten => _X.,n,ParkAndAnnounce(PARKED,,Local/${EXTEN}@parkinginfo)

...

[parkinginfo]
exten => s,1,NoOp(PARKEDAT=${PARKEDAT})
exten => s,n,...

So basically when the call gets parked, it "announces" the parking slot to a 
Local channel which executes in [parkinginfo].  Parkinginfo can write it to a 
db, SMS it to a skywriter, whatever you want.

It'd be nice to get this sent to a SIP phone and make parking just that much 
more useful, but as the guys say... patches welcome.  :-)
