I have an application where I am using AMI originate to start a call.
This bridges a call between an extension (1001) and my dialplan which waits for DTMF tones from the extension. If the user presses 8, then the dialplan should play another file, if the user presses 8 again it plays another file and so on and so on.
This works fine when digit 8 is presses from a SIP phone, but when trying to use the AMI action: playDTMF it doesn't work.
the tone is hear from the phone and I can see the activity in the asterisk CLI.
To be able to see it in the asterisk logs I first have to create a local channel to send the DTMF too.
While its being displayed in the asterisk CLI it doesn't step over to play the next file.
Here is an example of my asterisk CLI with key presses being made from a phone:
[2015-07-15 11:30:59.831] DTMF[14264][C-00000019]: channel.c:3945 __ast_read: DTMF end '8' received on SIP/1001-00000018, duration 180 ms

Compared to the same activity when the DTMF tone is generated by AMI:
[2015-07-15 11:30:59.693] DTMF[14264][C-00000019]: channel.c:4031 __ast_read: DTMF begin '8' received on SIP/1001-00000018

-- Executing [112@extensions:76] GotoIf("Local/112@extensions-00000009;2", "0?heard1:notheard8") in new stack
-- Goto (extensions,112,77)
This is my a snipet of my dialplan:
same =>n,NoOp(Play audioFile)
same =>n,ControlPlayback(dir/filename,4000,*,#,8,0)
same =>n,NoOp(${CPLAYBACKSTATUS})
same =>n,NoOp(${CPLAYBACKOFFSET})
same =>n,NoOP(${CPLAYBACKSTOPKEY})
same =>n,SET(VAR=${CPLAYBACKSTATUS})
same =>n,SET(FRE=1)
same =>n,GotoIf($["${VAR}" = "USERSTOPPED"]?heard1:notheard1)
My AMI command is:
action:playDTMF
channel:Local/112@extensions-00000009;2
digit:8
I'm assuming the DTMF is going to the wrong leg of the call and asterisk isn't passing it to ControlPlayback for recognition.
Could anyone advise how I might be able to get same =>n,ControlPlayback(dir/filename,4000,*,#,8,0) to recognise the DTMF tone sent via AMI?
