[asterisk-users] dealing with blind transfers to invalid extensions

[Jeronimo Romero]

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})
