while 與變數裡作運算

exten => _X.,1,Set(mb=${EXTEN})
exten => _X.,n,Set(x=1)
exten => _X.,n,While($["${SIP_HEADER(Diversion,${x})}" != ""])
exten => _X.,n,Set(mb="${SIP_HEADER(Diversion,${x})}")
exten => _X.,n,Set(mb=${CUT(mb,@,1):-4})
exten => _X.,n,Set(x=$[${x}+1])
exten => _X.,n,EndWhile()
exten=>  _X.,n,Goto(from-pstn,${mb},1)
