Hello! I'm sorry to hear about your tech issue. Different videoconferencing methods have different time limits for their free versions. If anything, I recommend you try a videoconferencing company that does not allow you to meet for less than an hour before shutting down the meeting. For example, Zoom has 40 min. free for non-paying users and endless time for users who buy a license, and I believe Skype has a similar function.
If the issue you described is with Wyzant's online tool, feel free to contact Wyzant Support about it. It could be a rare device-related glitch, and they're really helpful!
Hope this helps!
