*> You must therefore do it on a separate asterisk-manager connection* *> - and I would suggest separate thread as well* *>* Yes. I had to do that. In scenarios with high load, I got "timeout exception" when sending an action to get a response, using one managerConnection. It happened when I received many many events in same second. With a second managerConnection (which does not receive any events) now it is working OK.
