Have you tried prefixing PARKINGEXTEN with '__' (two underscores) on
the Set call in parkedcallstimeout?  That makes it a persistent
variable, which will be inherited by sub-channels, like after a Dial.

exten => _SIP011XX,n,Set(__PARKINGEXTEN=${PARKINGSLOT})

You might only need one underscore. 
For more info, see 'core show application set'.
