Park, Announce and bridge

OK I have a call get answered:

[who-r-u]
exten => s,1,Background(vm-rec-name)
exten => s,2,Wait(1)
exten => s,3,Record(/tmp/asterisk-stranger:gsm|5|15)
exten => s,4,Background(pls-hold-while-try)
exten => s,5,Goto(parkedcalls,70,1)
exten => s,6,Background(pls-stay-on-line)
exten => s,7,VoiceMail([email protected])
exten => s,8,Playback(Goodbye)
exten => s,9,Hangup

[parkedcalls]
exten => 70,1,Answer
exten => 70,2,SetMusicOnHold(default)
exten => 70,3,ParkAndAnnounce(inbound:/tmp/asterisk-stranger:vm-isonphone:at-following-number:PARKED|40|local/[email protected]|who-r-u,s,7)
exten => 70,4,Hangup

But I want to call a cell / hard line phone, announce the parked caller
and then pickup or let go to Voice Mail

I want to bridge the call to my cell phone if I chose to take it.
