我有一个dialplan我想要的，如果用户按任意键然后再次播放文件，但我不明白如何在拨号计划中获取 dtmf 值。这是我的拨号方案：
[callme]
exten => s,1,Answer
exten => s,n,Playback(demo/${FILENAME1})
首先如何获取 DTMF 值，如果用户按下任何键，则播放应该执行 2 次。但我想使用dialplan.

您可以使用 WaitExten [1] 来做到这一点：
[callme]
exten => s,1,Answer
exten => s,n,Playback(demo/${FILENAME1})
exten => s,n,WaitExten(3)
exten => s,n,Goto(s,1)
exten => 1,1,Noop(user pressed 1)
exten => 1,n,Goto(however-shall-go-to-when-pressed-1)
exten => 2,1,Noop(user pressed 2)
exten => 2,n,Goto(however-shall-go-to-when-pressed-2)
使用扩展模式 [2]：
[callme]
exten => s,1,Answer
exten => s,n,Playback(demo/${FILENAME1})
exten => s,n,WaitExten(3)
exten => s,n,Goto(s,1)
exten => X,1,Noop(user pressed ${EXTEN})
exten => X,n,Goto(however-shall-go-to-when-pressed-${EXTEN})
这正是您所要求的：
[callme]
exten => s,1,Answer
exten => s,n,Playback(demo/${FILENAME1})
exten => s,n,WaitExten(3)
exten => s,n,NoOp(going on - no dtmf detectd)
exten => X,1,Noop(user pressed ${EXTEN})
exten => X,n,Goto(s,1)
还可以查看背景星号应用程序 [3]。

您还可以使用应用程序读取。它确实要求不止一次，并导致更简单的拨号方案
[test]
;Read(variable[,filename[&filename2[&...]][,maxdigits[,options[,attempts[,timeout]]]]])
exten => s,1,Read(response,file_to_play,3,,4,10)
;will read into response variable,upto 3 digits and ask upto 4 times, timeout 10 sec
exten => s,2,GotoIf($[ "${response}" == "123"]?pin_ok,s,1)

感谢您回复我的解决方案，但我得到了这个解决方案，它对我有用......
[callme]
exten => s,1,Answer
exten => s,n,DumpChan()
exten => s,n,Playback(sclbrd/welcome)
exten => s,n,Wait(2)
exten => s,n,Set(i=1)
exten => s,n,While($[${i} != 3])
exten => s,n,Playback(sclbrd/${FILENAME1})
exten => s,n,Read(digit|sclbrd/press|1)
exten => s,n,Wait(1)
exten => s,n,GotoIf($["${digit}x" = "x"]?done:again)
exten => s,n(again),Wait(1)
exten => s,n,Set(i=$[${i} + 1])
exten => s,n,EndWhile()
exten => h,n(done),Wait(1)

这是读取 DTMF 值的简单示例上下文
[readDTMF]
exten => 113,1,Answer()
same => n,Read(NUMBER,vm-toenternumber)
same => n,Verbose(${NUMBER})
same => n,SayNumber(${NUMBER})
same => n,Hangup()
读取（变量到存储读取编号，[文件名到播放前读取][，其他选项]）
