The number         9335 3510 is sent by the telco.
The number 1414 02 9335 3510 is sent by an PABX.
The number      02 9335 3510 is the one which is the real telephone number:

exten => 93353510,1,Macro(call-local-sip,edwin,02${EXTEN})
exten => 0293353510,1,Macro(call-local-sip,edwin,${EXTEN})
exten => 14140293353510,1,Macro(call-local-sip,edwin,${EXTEN:4})

Is there a way to do this in one line?
