asterisk users - Mar 2005 - Why ${EXTEN} variable changes after Goto ?

Hi,

I'm trying to implement dynamic routing of incoming calls to local extension
if previous outgoing call was unanswered.
But after I do Goto to s-NOANSWER, variable ${EXTEN} changes to
's-NOANSWER'. I guess this is normal, but I don't understand why ?
How to
workaround on this one ?

Thanks in advance,

regards,

Rob.

[outbound-capi-ISDN]
exten => _0.,1,NoOp(Calling ISDN number ${EXTEN:1} on CAPI/7104370 from
${CALLERIDNUM})
exten => _0.,2,Dial,CAPI/7104370:b${EXTEN:1}|10|Tt
exten => _0.,3,Goto(s-${DIALSTATUS},1)
exten => _0.,103,NoOp(Calling ISDN number ${EXTEN:1} on CAPI/7104371)
exten => _0.,104,Dial,CAPI/7104371:b${EXTEN:1}|30|Tt
exten => _0.,105,Goto(s-${DIALSTATUS},1)
exten => _0.,205,Macro(outisbusy)

exten => s-NOANSWER,1,NoOp(NOANSWER - Setting dynamic autoroute for ISDN
number ${EXTEN:1} to local ext. ${CALLERIDNUM})
exten => s-NOANSWER,2,DBput(DYNAMIC/${EXTEN}=${CALLERIDNUM})
exten => s-NOANSWER,3,Congestion

exten => _s-.,1,Congestion
exten => _s-.,2,Macro(hangupcall)

${EXTEN} is the extension you are currently at.


exten => s,1,Goto(444)      ; ${EXTEN} = s
exten => 444,1,NoOp(bleh)   ; ${EXTEN} = 444

exten => someotherextension,1,NoOp()  ; $EXTEN = someotherextension

Save the original extension to a variable like ...

exten => _0.,1,SetVar(myvar=${EXTEN})
