[Asterisk-Users] "Context Picker" for interception and redirection

[Jason Lixfeld]

Got it working.. wow..  didn't think it would be this easy:

[test]
; Test SIP user's context
include => contextpicker

[contextpicker]
exten => _9NXXNXXXXXX,1,Set(LOCALEXT=${EXTEN:1})
exten => _9NXXNXXXXXX,2,GoTo(local-outbound-test,localout,1)
exten => _9NXXNXXXXXX,102,NoOp(seq 102 check)
exten => _91NXXNXXXXXX,1,Set(LDEXT=${EXTEN:1})
exten => _91NXXNXXXXXX,2,GoTo(cheapldprovider-outbound-test,ldout,1)
exten => _91NXXNXXXXXX,102,NoOp(seq 102 check)
exten => _8.,1,Set(INOCEXT={$EXTEN:1})
exten => _8.,2,GoTo(inoc-dba,s,1)
exten => _8.,102,NoOp(seq 102 check)

[local-outbound-test]
exten => localout,1,Dial(${LOCALIAXOUT}/${LOCALEXT},,r)
exten => localout,2,Playback(last-error-was)
exten => localout,3,SayDigits(${CAUSECODE})
exten => localout,4,Playback(tt-somethingwrong)
exten => localout,5,Hangup
exten => localout,102,NoOp(seq 102 check)

[cheapldprovider-outbound-test]
exten => ldout,1,Dial(${LDIAXOUT}/${LDEXT},,r)
exten => ldout,2,Playback(last-error-was)
exten => ldout,3,SayDigits(${CAUSECODE})
exten => ldout,4,Playback(tt-somethingwrong)
exten => ldout,5,Hangup
exten => ldout,102,NoOp(seq 102 check)
