识别DTMF是否按下Asterisk IVR

Question

我需要帮助来确定在Asterisk IVR上是否按下了DTMF。 情景是： 我想根据DTMF是否按下来调用AGI脚本。如果按下DTMF（IVR菜单）无关。 如果没有按DTMF调用和AGI并保存信息。

任何帮助，高度赞赏。

我使用星号，11

[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()
