Re: [Asterisk-java-users] Asynchrnous calls

[Gaëtan M. <gm...@ea...>]

Hi,

Another solution is to use

sendAction(ManagerAction action, SendActionCallback callback)


and pass null as callback, as you're not interested in the result.


The code specifically handle the null case with a nice comment :)

// if the callbackHandler is null the user is obviously not interested
// in the response, thats fine.
         if (callback != null)
         {
             synchronized (this.responseListeners)
             {
                 this.responseListeners.put(internalActionId, callback);
             }
         }

Kind regards

Gaetan
