Auto Att Dial to diff chan

Asterisk Asterisk Support

I would like callers to be able to dial known extension from my Auto Attendant… "If you know your parties extension, you may dial it now."
Works fine if all extensios are the same type. How can I Dial some Sip, some Sccp and a few Zap?
exten => s,1,Answer
exten => s,2,Wait(1)
exten => s,3,SetMusicOnHold(internal)
exten => s,4,DigitTimeout,2
exten => s,5,ResponseTimeout,10
exten => s,6,Background(/tmp/main_auto_att)
exten => s,7,NoOP,${EXTEN}

;dial collected extension
exten => _1XXX,1,Dial(sip/${EXTEN},10,r) ;;; needs to allow all types!
exten => _1XXX,2,SayDigits(${EXTEN})
exten => _1XXX,3,Playback(vm-isunaval)
exten => _1XXX,4,VoiceMail(u${EXTEN})
