[Asterisk-java-users] Getting result of an dial plan Application

[Brett S. <bs...@no...>]

I'm calling an application (txfax) using an originate.
I've managed to monitor events and wait for a hangup event so that I 
know that the application has completed executing.
The question is how do I get the return value from the application.
Reading the source of txfax (app_txfax.c) it appears that txfax returns 
a value of -1 if the call fails.
In further reading it appears that many applications increment the 
priority in some manner.
If so can I get the return value be getting the priority and subtracting 
some base value?
If that is the technique then how do I get the priority value?


And the code
        originateAction = new OriginateAction();
            originateAction.setChannel(channel.getChannelName() + "/"
                    + Fax.getTelephoneNo(recipient));
            originateAction.setContext(channel.getContext());
            HashMap<String, String> variables = new HashMap<String, 
String>();
            Configuration config = Configuration.getInstance();
            variables.put("MaxRetries", "1");
            variables.put("RetryTime", new Integer(config.getRetryTime())
                    .toString());
            variables
                    .put("WaitTime", new 
Long(config.getWaitTime()).toString());

            originateAction.setVariables(variables);
            originateAction.setApplication("txfax");
            String data = fax.getTiffFile().getFile().getAbsolutePath()
                    + "|caller";
            if (config.isDebugTxFax())
                data += "|debug";
            originateAction.setData(data);
            originateAction.setPriority(new Integer(config.getPriority()));
            originateAction.setTimeout(new Long(config.getTimeOut()));


Any help would be appreciated.
