asterisk - 识别 Asterisk IVR 上是否按下了 DTMF

Question

我需要帮助来确定 Asterisk IVR 上是否按下了 DTMF。场景是：我想根据DTMF是否按下来调用一个AGI脚本。如果按下 DTMF(IVR Menus)，则无事可做。如果没有按下 DTMF 呼叫和 AGI 并保存信息。

非常感谢任何帮助。

我正在使用星号 11

使用超时选项

[mainmenu]
  exten => s,1,Answer
  exten => s,2,SetMusicOnHold(default)
  exten => s,3,DigitTimeout,5
  exten => s,4,ResponseTimeout,10
  ;SAI menu - 1 for tech support, 2 for voicemail, 3 for echo test
  exten => s,5,Background(sai-welcome)
  exten => s,6,Background(sai-choose)

  ; Tech Support
  exten => 1,1,AGI(dima-test.agi)
  exten => 1,2,SetGlobalVar(ACCOUNTCODE=${callerid})
  exten => 1,3,SetVar(testcallerid=${callerid})
  exten => 1,4,Background(sai-reptech-welcome)
  exten => 1,5,Queue(rep-tech)

  ; Leave Voicemail
  exten => 2,1,VoicemailMain()
  exten => 2,2,Hangup


  ; Play Music-on-Hold
  exten => 5,1,MusicOnHold(default)
  exten => 5,2,Goto(mainmenu,s,6)
  ; #=hangup
  exten => #,1,Playback(sai-thanks)
  exten => #,2,Hangup

  exten => t,1,Goto(#,1)         ; If they take too long, give up
  exten => i,1,Playback(invalid) ; "That's not valid, try again"
