The problem is that the reader thread for the asterisk-manager connection is used to handle the event, so if you push out any manager command/action you can't get the response because you are holding the reader thread. You must therefore do it on a separate asterisk-manager connection - and I would suggest separate thread as well, I can't recall if there is anything like ThreadLocal used in the manager connection implementation but it would be the safest option.
