Hi jon

What system is it?

you need to set the transfer capability

eg
exten => _X.,1,gotoif($[${TRANSFERCAPABILITY}=DIGITAL]?8:)
exten => _X.,2,Noop
exten => _X.,3,ringing
exten => _X.,4,set(CDR(accountcode)=${EXTEN})
exten => _X.,5,Noop
exten => _X.,6,dial(ZAP/g2/${EXTEN},,r)
exten => _X.,7,hangup
exten => _X.,8,Set(CHANNEL(transfercapability)=DIGITAL)
exten => _X.,9,dial(ZAP/g2/${EXTEN})
exten => _X.,n,hangup
