Re: [Freeswitch-users] Problems getting dtmf events - code and debug now attached

2 Sep 2010

      It has not made a difference when I used the playback_terminators .

My problem happens when the code gets to the while loop, this is past the playback command.

As can been seen from the debug log the code does go into the while loop and waits for events it catches all events apart from dtmf. It seems the detection of dtmf events is not happening after the playback command

[DEBUG] src/esl.c:1042 esl_recv_event() RECV MESSAGE
Event-Name: SOCKET_DATA
Content-Length: 5015
Content-Type: text/event-plain

got event
test event
wait for event

The full test script: 

require 'rubygems'
require "ESL"
require 'socket'
include
 Socket::Constants

#Log
ESL::eslSetLogLevel(7)

@ring_ring = "tone_stream://%(400,200,400,450);%(400,2200,400,450);loops=2"

    def pick_up_call
        @con.execute("answer")
        @con.setEventLock("true")
        @con.execute("sleep", "1000")
        @con.execute("playback", @ring_ring)
    end

bind_address = "127.0.0.1"
bind_port = 8084

socket = Socket.new(AF_INET, SOCK_STREAM, 0)
sockaddr = Socket.sockaddr_in(bind_port, bind_address)
socket.bind(sockaddr)
socket.listen(5)

puts "Listening for connections on #{bind_address}:#{bind_port}"
loop do
  client_socket, client_sockaddr = socket.accept
  pid = fork do
    @con =
 ESL::ESLconnection.new(client_socket.fileno)
    info = @con.getInfo
    @uuid = info.getHeader("UNIQUE-ID")
    @con.sendRecv("myevents")
    @con.sendRecv("divert_events on")

    pick_up_call

        while @con.connected
puts "wait for event"
                e = @con.recvEvent
puts "got event"
                if (!e.nil?)
puts "test event"
                    name = e.getHeader("Event-Name")
                    break if name == "SERVER_DISCONNECTED"

         if name == "DTMF"
                        digit = e.getHeader("DTMF-DIGIT")
                        duration = e.getHeader("DTMF-DURATION")
                        puts "*** dtmf #{digit} #{duration}"
                    end
                end
        end

    puts "Connection closed"
  end

  Process.detach(pid)
end

I am trying to catch dtmf events but am having problems. It seems no dtmfs are being recieved. I can filter to other events and it gets picked up so this section of the code is doing the indented action of getting events. 

However I notice that during the execution of the playback command while the sound file is playing if a key press is done at this time the dtmf does get received.

So my thought are what conditions does the playback command set in order to be able to have dtmf get recognized.
