I'd suggest something like

exten = _9.,1,Dial(Zap/g3/9|20|t)  ;dial "9" for outbound line
exten = _9.,2,Wait(1)              ;wait 1s for dialtone, PBX may take longer
exten = _9.,3,SendDTMF(${EXTEN:1}) ;send remaining digits as DTMF

If you have more than one (9...) case, you may want to use a macro.
