[Asterisk-java-users] Re: Timeout when hanging up

[<be...@mo...>]

Hello!

I'm trying to do exactly the same thing as in the Timeout when hanging 
up topic. The difference is that instead of SIP, I want to use Zap 
channels (well zap compatible aculab card).

I have a problem with receiving events to the call manager.
What I'm trying to do is to call a phone, and as soon as I get a ringing 
tone, I want to hangup.
Therefore I'm trying to get the NewChannelEvent with state ringing.

When I use SIP, everything is fine, the event shows up just like it 
should, but when I'm using a SIP VOIP provider or a Zap (aculab) card, 
the event is not comming to the call manager.

I can see in the asterisk console that the card event is occuring, and 
the card driver then sends AST_CONTROL_RINGING to the asterisk queue.

Ufortulately the event is not passed by the call manager.
The only events that are sent are:

net.sf.asterisk.manager.event.NewChannelEvent, State:Down
net.sf.asterisk.manager.event.NewCallerIdEvent
net.sf.asterisk.manager.event.HangupEvent
net.sf.asterisk.manager.event.OriginateFailureEvent
net.sf.asterisk.manager.event.DisconnectEvent

When I'm calling using local SIP phone, the events go through:
net.sf.asterisk.manager.event.NewChannelEvent: State: Down
net.sf.asterisk.manager.event.NewCallerIdEvent:
net.sf.asterisk.manager.event.NewChannelEvent: State: Ringing
net.sf.asterisk.manager.event.HangupEvent:
net.sf.asterisk.manager.event.PeerStatusEvent:

Is there some configuration file in asterisk that needs to be changed in 
order for zap channels to report the NewChannelEvent every time?

what do you mean by "when i use sip its fine but when i am using a sip
voip provider it is not"? isnt a sip voip provider sip, too?

could it be that the difference between the cases when it works and when
not is that you are sometimes looking at incoming channels and sometimes
at outgoing?

OK here's what I'm doing:

The idea is to check the regular phones, by calling them and hanging up 
as they start ringing, so we're talking about outgoing calls.

Now, there are 3 cases:

- SIP to SIP (a software phone),
- calling regular phones using a VoIP provider over SIP,
- calling regular phones using Aculab card (based on Zaptel), over E1 
line using Q.931 protocol.

Cases 1 and 2 are just for testing.
So far, the only case that works is the first one (the NewChannelEvent 
reaches the call manager). In the other cases, the event does not reach 
the call manager.

As for the case 3 I can see that the card sends the event to the 
asterisk. The card driver uses the ast_queue_control function to send 
the event to the asterisk event queue, so I guess that's fine.

Here's the code that I'm using in lava:

     private ManagerConnection managerConnection;

     public HelloEvents() throws IOException
     {
         ManagerConnectionFactory factory = new ManagerConnectionFactory();

         this.managerConnection = "host",
                 "manager", "pa55w0rd");
     }

     public void run() throws IOException, AuthenticationFailedException,
             TimeoutException, InterruptedException
     {
         managerConnection.login();
         // register for events
         managerConnection.addEventHandler(this);

         OriginateAction originateAction;
         ManagerResponse originateResponse;

	String phoneNumber = "124332432";

         originateAction = new OriginateAction();
         originateAction.setCallerId("\"bercik\" <123143255>");
         originateAction.setApplication("Wait");
         originateAction.setData("1");
         originateAction.setTimeout((Long.valueOf("30300")));
         originateAction.setAsync(new Boolean(true));

         try
         {
         	//Using sip works fine
		//originateAction.setChannel("SIP/bercik");
         	originateAction.setChannel("Aculab/1/"+phoneNumber);
         	// send the originate action and wait for a maximum of
         	// 30 seconds for Asterisk to send a reply
	        originateResponse = 
managerConnection.sendAction(originateAction,30000);
         }
         catch (TimeoutException e) {
         	e.printStackTrace();
		}
         // wait 10 seconds for events to come in
         Thread.sleep(30000);
         // and finally log off and disconnect
         managerConnection.logoff();
     }

     public void handleEvent(ManagerEvent event)
     {
         // just print received events
         System.out.println(event.toString());
         if (event instanceof NewChannelEvent)
         {
             NewChannelEvent cevent = (NewChannelEvent) event;
             System.out.println(cevent.getState());
             if (cevent.getState().compareToIgnoreCase("Ringing") == 0)
             {
             	System.out.println("Got ringing, hanging up");
                  HangupAction hangup = new HangupAction();
                  hangup.setChannel(cevent.getChannel());
                  try
                  {
                  managerConnection.sendAction(hangup, null);
                  }
                  catch (Exception e)
                  {
                  e.printStackTrace();
                  }
             }
         }
     }

       public static void main(String[] args) throws Exception
     {
         HelloEvents helloEvents;

         helloEvents = new HelloEvents();
         helloEvents.run();
     }
}

Now, what happens is, the phone is just ringing and I can answer, but no 
NewChannelEvent is comming, when the phone is ringing.

Any ideas, on why is this happening?

Thanks.

Re: [Asterisk-java-users] Re: No NewChannelEvent that indicates ringing for remote phones (was: Timeout when hanging up)

[Stefan R. <sr...@re...>]

Robert,

thanks for your clarification. It seems it only works if the phone is
local to Asterisk, i.e. directly connected. Is this correct?
I am not sure if it is a bug that Asterisk does not generate "Ringing"
events for those channels or if its the desired behaviour. In any case i
doubt its an Asterisk-Java specific problem so its probably best to
either post it to the asterisk-useres list or report it as a bug on
Asterisk's bug tracker.

Hey! That's a bright conclusion!

OK! I'll do just that then.
