             Summary: Channel Hangup after DTMF during Playback
                 Key: ASTERISK-25563
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25563
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Applications/app_playback, Resources/res_agi
    Affects Versions: 13.6.0, 13.4.0
         Environment: CentOS 7 in KVM Virtual Machine
            Reporter: Martin Vogt


We have an Adhearsion based AGI application.
In Adheasion we use the function menu that starts the playback function in asterisk.
If we send a dtmf to the channel during the playback, the normal behavior should be that asterisk stops the playback an continues the agi application. but we get a hangup on the channel.

extensions.conf:
[from_sip]
exten => 777,1,NoOp(Extension: ${EXTEN})
exten => 777,2,Set(AGI_HOST=127.0.0.1)
exten => 777,3,Goto(menu_test,${EXTEN},1) 

[menu_test]
exten => _777,1,AGI(agi:async)  

adhearsion dialplan:
class TestController < Adhearsion::CallController

  def run

    answer

    # menu %w(file://vm-press file://vm-first file://vm-for file://vm-password), :limit => 1, :timeout => 5.seconds do
    menu %w(file://vm-press file://vm-first file://vm-for file://vm-password), :terminator => '#' do
      match [1, 2, 3] do |dial|
        logger.info "Caller pressed #{dial}"
      end
    end

    play 'file://vm-pls-try-again'

    #####################################
    # this menu is never audible
    #####################################
    menu %w(file://vm-press file://vm-first file://vm-for file://vm-password), :limit => 1 do
      match [1, 2, 3] do |dial|
        logger.info "Caller pressed #{dial}"
      end
    end

    hangup

  end
end

SIP/111 dials 777 ---> 777 at from_sip ---> 777 at menu_test ---> AGI ---> menu (adhearsion) ---> Playback(asterisk) ---> dtmf to channel ---> hangup

We did a tcpdump and found out that adhearsion is not sending the hangup request to asterisk. So we think asterisk clears the call on its own.

We have already opened an issue on the adhearsion bug tracker: https://github.com/adhearsion/adhearsion-asr/issues/29 
The Adhearsion developement team also thinks that asterisk clears the call by itself.

debug logs follow...
