Php 如何在拨号计划中获取dtmf值

我有一个

dialplan

，其中我想要的是，如果用户按下任何键，然后再次播放文件，但我不知道如何在dialplan中获取dtmf值。 这是我的计划：

[callme]  
exten => s,1,Answer 
exten => s,n,Playback(demo/${FILENAME1})

---

首先，如何获取DTMF值，如果用户按任意键，则播放应执行2次。但我想使用

拨号计划管理所有这些内容
您可以使用WaitExten[1]来完成：

[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)

还要看一下背景星号应用程序[3]

[3] 您还可以使用应用程序读取。它确实要求多次，结果就不那么复杂了

[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)

谢谢你回复我的解决方案，但我得到了这个解决方案，它对我有效

[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)

下面是一个读取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（用于存储读取编号的变量，[读取前播放的文件名][，其他选项]）
