Re: [Asterisk-java-users] EVENT LISTENER PROBLEM

[Daniele R. <dan...@gm...>]

Hi Stefan,
thanks very much for usefull information.
We now with the dtmf events patch can be able to detect press of
digits. We have a small problem on calls that are no asnwer, infact is
throw an exception:
vento new propertyChange

We have printed the values of the channel and as you can see and the
name is NULL. So is throw the exception. We have used the
OriginateCallback in order to detect events in this mode:

static class MyOriginateCallback implements OriginateCallback{
        private final int i;

        private MyOriginateCallback(int i) {
            this.i = i;
        }

        @Override
        public void onDialing(AsteriskChannel channel) {
            channel.addPropertyChangeListener(new PropertyChangeListener() {

                @Override
                public void propertyChange(PropertyChangeEvent evt) {
                    System.out.println("Evento new propertyChange " +
evt + " " + i);
                }
            });
            channel.addDTMFListener(new DTMFListener() {

                @Override
                public void onDtmfStart(DTMF dtmf) {
                    log.debug("Dtmf start "+dtmf);
                }

                @Override
                public void onDtmfEnd(DTMF dtmf) {
                    log.debug("Dtmf end "+dtmf);
                }
            });
            log.debug("Dialing " + i);
        }

        @Override
        public void onSuccess(AsteriskChannel channel) {
            log.debug("Success " + i);
        }

        @Override
        public void onNoAnswer(AsteriskChannel channel) {
            log.debug("No answer " + i);
        }

        @Override
        public void onBusy(AsteriskChannel channel) {
            log.debug("Busy " + i);
        }

        @Override
        public void onFailure(LiveException cause) {
            log.debug("Failure" + i);
        }
    }

....
....
asteriskServer.originateAsync(action, new MyOriginateCallback(i));


It's correct the use of the Callback? Is a small bug the problem or
I've make a mistake?

Thanks very much

Best regards

Daniele
