Thanks.. Issue Closed.. I changed the code to remove the "slash" and it works..
[fop2-park]
exten => _X.,1,Set(ARRAY(RETURN_EXTENSION,RETURN_CONTEXT)=${CUT(EXTEN,:,1)},${CUT(EXTEN,:,2)})
exten => _X.,n,ParkAndAnnounce(PARKED,,Console/dsp,${RETURN_CONTEXT},${RETURN_EXTENSION},1)
exten => _X.,n,Goto(${RETURN_CONTEXT},${RETURN_EXTENSION},1)
exten => _X.,n,Hangup
