[Asterisk-java-users] Excetpion when trying use the channel of live api

[jeff l. <ll...@gm...>]

Hey guys,

  I'm not quite familiar with live api and a little confused by some concept
in it.  What does the channel stand for(same as fastagi)? Why do I get
NoSuchChannelException when trying to use the channel when
NewAsteriskChannel is fired.Some codes:

    public void onNewAsteriskChannel(AsteriskChannel channel){
        System.out.println("Caller ID: " + channel.getCallerId());
        System.out.println ("Name: " + channel.getName());

        try {

//            channel.startMonitoring("/tmp/mlu/live/test.wav");       I do
find two audio files,so this one not failed
//            channel.redirect("extensions-shanghai-sip","628",0);  Failed
              channel.playDtmf("1");
    Failed
        } catch (ManagerCommunicationException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (NoSuchChannelException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
  Logs:

Which version of Asterisk are you running?
Afair playDtmf is only supported in 1.4. With 1.2 you might receive this
(somewhat misleading) exception.
