IVR星號撥號計划因無效按鍵而無限期

Question

我是 asterisk 的新手，我正在 extensions.conf 中做撥號計划。 我正在創建一個簡單的 IVR，其中客戶的無效按鍵應僅重復兩次。 之后它應該斷開連接。 但這里循環無限期。 請通過檢查下面的代碼提供幫助

[ivr1]
exten => 100,1,Goto(ivr1,s,1)
exten => s,1,Set(VOLUME(TX)=20)
exten => s,n,Answer(500)
same => n(loop),Background(playfile)
same => n,WaitExten(10)
exten => 1,1,Dial(SIP/ivr_218/xxxx,30,m(waiting-audio))
exten => 1,2,Dial(SIP/ivr_218/xxxx,30,m(waiting-audio))
same => n,Hangup(${ActionID},keypress1)
exten => 2,1,Dial(SIP/ivr_218/xxxx,30,m(waiting-audio))
same => n,Hangup(${ActionID},keypress2)
exten => i,1,Playback(playfile_for_invalid)
same => n,Goto(s,loop)
exten => t,1,Playback(playfile_for_noresponse)
same => n,Goto(s,loop)
exten => n,Hangup()

你可以像這樣添加計數器，

[ivr1]
exten => 100,1,Goto(ivr1,s,1)
**exten => s,1,Set(Counter = 0)**
exten => s,1,Set(VOLUME(TX)=20)
exten => s,n,Answer(500)
same => n(loop),Background(playfile)
same => n,WaitExten(10)
exten => 1,1,Dial(SIP/ivr_218/xxxx,30,m(waiting-audio))
exten => 1,2,Dial(SIP/ivr_218/xxxx,30,m(waiting-audio))
same => n,Hangup(${ActionID},keypress1)
exten => 2,1,Dial(SIP/ivr_218/xxxx,30,m(waiting-audio))
same => n,Hangup(${ActionID},keypress2)
exten => i,1,Playback(playfile_for_invalid)
**same => n,Set(Counter=$[${Counter}+1])
same => n,GotoIf($["${Counter}"<"2"]?s,loop)
same => n,Hangup()**
exten => t,1,Playback(playfile_for_noresponse)
same => n,Goto(s,loop)
exten => n,Hangup()
