As a habit, I do not force users to dial 9 or any other prefix of any
kind
to access external lines. You can just check the dialled number and prefix
with appropriate digits appropriately. See below. NOTE: THIS IS
US-CENTRIC!!
but can be easily made to work for any country.

exten => _1XXXXXXXXXX,1,Goto(outgoing,${EXTEN},1)

; Check for 10 digit NANP
exten => _XXXXXXXXXX,1,SetVar(PREFIX=1)
exten => _XXXXXXXXXX,2,Goto(outgoing,${PREFIX}${EXTEN},1)
; Check for 7 digit NANP
; Then add "1" and the location area code

exten => _XXXXXXX,1,SetVar(PREFIX=1925)
exten => _XXXXXXX,2,Goto(outgoing,${PREFIX}${EXTEN},1)
; Check for emergency numbers

exten => 911,1,Goto(emergency,911,1)

; Check for other special numbers and direct to repective contexts.

[outgoing]
exten => _X.,1,ChanIsAvail(${PSTNCHANNEL})
exten => _X.,2,NoOp(AvailChannel=${AVAILCHAN})
exten => _X.,3,Set(DialChannel=${CUT(AVAILCHAN,,1)})
exten => _X.,4,Dial(${DialChannel}/${EXTEN},100)
exten => _X.,5,Congestion
exten => _X.,105,Congestion
My problem with this type of dialplan is that users must wait for
DigitTimeout before the call is processed.
