[macro-setDialednumberFromSipHeader]
;
; We extract the DIALEDNUMBER from SIP header
; which is of the form <sip:CALLEDNUMBER at OurAsteriskIPAddress>

exten => s,1,Set(__DIALEDNUMBER=${SIP_HEADER(TO):5})
exten => s,n,Set(__DIALEDNUMBER=${CUT(DIALEDNUMBER,@,1)})
exten => s,n,GotoIf($["${DIALEDNUMBER:0:1}" != "+"]?numberIsOK)
exten => s,n,Set(__DIALEDNUMBER=${CUT(DIALEDNUMBER,+,2)})

exten => s,n(numberIsOK),NoOp()
exten => s,n,Set(CDR(dest)=${DIALEDNUMBER})

done ;-)
