Hi @Ellen_m65, and welcome to the Zoom Community! I hope your meetings go well. To ensure everything is good to go, I'd recommend visiting http://zoom.us/test and joining a test meeting.

Thanks Bri, I did that and it worked great. I then had a friend test it with me so I’ll be sure to be ready for my meeting. Although we have FaceTime on our phones, we finished our our conversation via zoom. It came up and said my first free zoom meeting was about to expire. Does this mean future meetings are doing to cost me?  Here’s the situation, I have an evaluation in January to see if I pass to receive a kidney transplant. They sent me an email to download this zoom for a phone conversation the week before my evaluation. So when they call me the week before, I need to make sure I have this zoom ready. Will it cut off after 40 minutes? I have no idea how long the phone zoom meeting will go. How can I ensure that I am set? 
thank you, Ellen
