Adobe Connect automatically records then plays back across meeting audio - how to stop this?

Adobe Connect automatically records then plays back across meeting audio - how to stop this? It seems that it only happens when you ask the system to call you rather than if you dial in - however it's very frustrating and I would have to include a full list of the dial in numbers in meeting agenda, also ask them specifically not to receive a call from the system. I have just had a very disrupted meeting as the recording reaches its limit and automatically lays back across normal audio. It has happened a few times. How to prevent this? Thanks. It's difficult to tell which version of the app I have, too...
