Well, i fix context by adding "]" in fop2_override...
Was:
[fop2-park] exten => _X.,1,Set(ARRAY(RETURN_EXTENSION,RETURN_CONTEXT,PARKBUTTON)=${CUT(EXTEN,:,1)},${CUT(EXTEN,:,2)},${CUT(EXTEN,:,3)}) exten => _X.,2,GotoIf($["${PARKBUTTON}" = "PARK/default"?5) exten => _X.,3,GotoIf($["${PARKBUTTON}" = ""?5) exten => _X.,4,Set(PARKINGLOT=${PARKBUTTON:5}) exten => _X.,5,Park(,sc(${RETURN_CONTEXT},${RETURN_EXTENSION},1))
Fixed
