Timeout on SendAction

[lameventanas]

I have a program with an AgentCalled event handler that needs to check the extension's state.

It looks like this:

ExtensionStateAction esa = new ExtensionStateAction();
esa.Exten = myExtension;
ManagerResponse res = manager.SendAction(esa);

This always times out, but when I connect to asterisk's manager via telnet I can do this:

Action: ExtensionState
ActionID: 2
Exten: 1020

Response: Success
ActionID: 2
Message: Extension Status
Exten: 1020
Context: default
Hint: SIP/1020
Status: 1

I'm aware of #188, but here the manager connection (and callbacks) run in a single thread, I don't have multiple instances (I'm not even sure what that means).

As a workaround, I don't call SendAction() anymore, but I implemented a second event handler to handle the ExtensionState event, which always comes shortly after AgentCalled event. Then both event handlers have some crude logic to determine they are related, but this is ugly and less reliable.

If you don't know what it means to have multiple instances, you might want to share you connection and disconnection code too.

There are multiple open issues about TimeoutExceptions being thrown where it makes no sense. Some code to reliably reproducing the issue would help a lot.
Was one other issue where I could reproduce the issue, but that case kinda went nowhere after the reporter didn't reply.
See: #123

Here is a small console program to reproduce it.
It reacts to any UserEvent.
