Re: [Asterisk-java-users] Reading a variable after call ends

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

Hi yves,
sorry for the lack of details.

I do this:

OriginateAction action = createAction(telefonata);
                try {
                    telefonata.onCreate();
                    asteriskServer.originateAsync(action, new
MyOriginateCallback(telefonata));
                } catch (ManagerCommunicationException e) {
                    log.error(telefonata.getId() + " ha generato un
errore", e);
                    telefonata.onFailure();
                }

    private class MyOriginateCallback implements OriginateCallback {

        private final TelefonataInterface telefonata;

        private MyOriginateCallback(TelefonataInterface telefonata) {
            this.telefonata = telefonata;
        }

@Override
        public void onDialing(final AsteriskChannel channel) {
            log.debug("On dialing comunicazione " + telefonata.getId());
            telefonata.onDialing();
            channel.addPropertyChangeListener(new PropertyChangeListener() {

                @Override
                public void propertyChange(PropertyChangeEvent evt) {
                  if (evt.getSource() instanceof AsteriskChannel) {

                        // EVENTO DI HANGUP
                        if (channel.getState() == ChannelState.HUNGUP) {

                            String hangupCauseText = "";
                            if (channel.getHangupCauseText() != null)
                                hangupCauseText =
channel.getHangupCauseText();
                            telefonata.onHangupEvent(channel);
                        }

                }
            });
        }

        @Override
        public void onSuccess(AsteriskChannel channel) {
            log.debug("Success " + telefonata.getId() + " " + channel);
            log.debug("La comunicazione è iniziata alle " +
channel.getDateOfCreation());
            telefonata.onSuccess();
        }

        @Override
        public void onNoAnswer(AsteriskChannel channel) {
            log.debug("NoAnswer " + telefonata.getId() + " " + channel);
            telefonata.onNoAnswer();
        }

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

        @Override
        public void onFailure(LiveException cause) {
            log.debug("OnFailure(...)' - " + telefonata.getId());
            telefonata.onFailure();
        }

}

My dialplan:

[test]
exten => s,1,Answer()
exten => s,1,Playback(smt)
exten => 3,n,Set(variable=This is the value of the variable)
exten => s,n,Hangup()

I've a PropertyChangeListener so I can know when the call hangup. I'd like
to get the value of the variable into Javacode in my method
onHangupEvent(), so when the call end I need to read that variable.
I know that I can create a class that extends BaseAgiScript to get the
variable, but there is another way to do this? Would be more convenient to
have the variable in the method onHangupEvent() for my case.

Thanks
