asterisk users - Oct 2006 - dealing with blind transfers to invalid extensions

Running Asterisk 1.2.8  kernel  2.6.13.4-1. 
Everything in my dialplan seems to be working well except for one
problem. 
When calls are blind transferred to an invalid extension I would like
the call to go to the operator on ext 1000?
What is the best way to do this? Thanks in advance 


Here's a snippet of my extensions.conf

[default]
exten=>_10XX,1,Macro(stdexten,${EXTEN},SIP/${EXTEN})
exten=>_11XX,1,Macro(stdexten,${EXTEN},SIP/${EXTEN})
include=>record
include=>parkedcalls
include=>voicepulseoutgoing
include=>conferences
include=>voicemail


[macro-stdexten]
exten=>s,1,Dial(${ARG2},20,t)
exten=>s,2,Goto(s-${DIALSTATUS},1)
exten=>s-NOANSWER,1,Voicemail(u${ARG1})
exten=>s-NOANSWER,2,Goto(default,s,1)
exten=>s-BUSY,1,Voicemail(b${ARG1})
exten=>s-BUSY,2,Goto(default,s,1)
exten=>_s-.,1,Goto(s-NOANSWER,1)
exten=>a,1,VoicemailMain(${ARG1})

I do the following:


[direct-to-voicemail]

; **************************************************
; Allow anybody to send a call directly to voicemail
; by pre-pending a 0 to the destination extension.
; Checks to see if voice mail box exists, if not
; Tells the callee that no such vm box exists and
; then transfers them to the operator
; **************************************************

exten => _04XXX,1,Set(_direct_vm=${EXTEN:1})
exten => _04XXX,2,MailboxExists(${direct_vm}@sip)
exten => _04XXX,3,Goto(s-${VMBOXEXISTSSTATUS},1)

exten => s-FAILED,1,SayDigits(${direct_vm})
exten => s-FAILED,2,Playback(vm-nobox)
exten => s-FAILED,3,Playback(pbx-transfer)
exten => s-FAILED,4,Goto(incoming,s,1)

exten => s-SUCCESS,1,Set(CALLBACK=${DB(vmcallback/${direct_vm})})
exten => s-SUCCESS,2,GotoIf($["${CALLBACK}" = 
"YES"]?s-SUCCESS,3:s-SUCCESS,4)
exten => s-SUCCESS,3,System(/usr/local/bin/vm-callout.sh ${direct_vm})
exten => s-SUCCESS,4,Voicemail(u${direct_vm}@sip)
exten => s-SUCCESS,5,Hangup()
