[VoIP] ASR Program

[Lee Spenadel]

Peter, thank you.  Where did you develop this code?  The code I grabbed was
off of the archives, which is not as intricate.

Many thanks
Lee

Lee, you don't appear to have the line which sets the language, in which
case
it defaults to German.  Here's the one I'm using from the wiki.......

[operatordemo] 
exten => s,1,Ringing() 
exten => s,n,Set(l=2) ; U.S. English 
exten => s,n,Wait(1) 
exten => s,n,Answer 
exten => s,n,Ringing() 
exten => s,n,Noop(${CALLERID(all)}) 
exten => s,n,ASR(t1l${l}d) ; 1 millisecond to prime the server connection
after long idle time 
exten => s,n,Wait(1) 
exten => s,n(num),Playback(numplse) ; "Number please" 
exten => s,n(asr),ASR(t20000l${l}d) ; Accept digits for up to 20 seconds
with
default timeout 
exten => s,n,Noop(${ASRMSG}) 
exten => s,n,Gotoif($"${ASRMSG}" != "Server timeout"?want) ; Recognition
failure 
exten => s,n,Playback(server&connection-failed) 
exten => s,n(want),Playback(numwant) "What number are you wanting, please?" 
exten => s,n,Goto(asr) 
; 
exten => _digits.,1,Noop(${ASRMSG}) 
exten => _digits.,n,SayDigits(${EXTEN:6}) ; tell him what we heard him say 
exten => _digits.,n,Playback(trying) ; "I'm trying to get them" 
exten => _digits.,n,Goto(${EXTEN:6},1) 

; include here enough of a dialplan to validate the number given 
; or maybe even an enum lookup. 

exten => 21,1,Goto(regularcontext,${EXTEN},1) ; for example, 21 might be a
valid extension 
exten => _NXXNXXXXXX,1,Goto(regularcontext,${EXTEN},1) ; and we might have
local ten digit numbers 
;etc 

exten => i,1,Playback(invalid) ; if it doesn't match the above, give him
another chance 
exten => i,2,Goto(s,want) ; without having to hang up.
