Hello all, I'm new here. I have a McBook Pro and a large monitor attached. I bought a camera and it sits on top of the monitor.  When in a meeting I can hear everyone else fine, my voice is muffled and they can barely hear me. I've gone through the tutorial for audio and have followed the instructions and nothing changes. Is this a problem with Zoom, my computer or the camera and how can I tell. Help please

Trying to join a meeting that has a zoom link on a website that is connected to calendar on their website. I click the link and and when I click on more details or add to my calendar the calendar opens and then does absolutely nothing. I cannot join the zoom meeting no matter what.  

Suggestions?

When I go into my zoom account and start a recurring meeting, so as a host I've already started the meeting.  My participants go into their e-mail and click on the link I've sent them for this meeting and they get the message 'host is in another meeting' - ??? so I have to close the meeting and go into their e-mail and go into my own meeting that way - why is this - 

Using Zoom to multi-stream for a Live Call-In Show where my client can be seen on Zoom video via streamed his media platforms , (but audio only for participants) where callers dial the 877 Zoom number to ask questions to my client. A couple questions.

1) How do I remove meeting ID requirement for incoming phone only callers so that they can get to the waiting room? (I've set waiting room setting to "everyone" goes there upon entering) But when I do a test and call the 877 # it is asking for a meeting ID.
2) Once in waiting room, how do I communicate with a caller to vet them before admitting them (audio only) to my client to ask their question. Any help appreciated, Thanks. 

Good morning,
my school uses the basic version of the zoom. We have set permanent links and a password for the meetings. Unfortunately, for a few days an uninvited guest connects to classes (impersonating students) and interferes with the class by shouting offensive texts at one of the students of a given class, and then disconnects immediately.

Is there any chance to discover this person's IP? Who that person is?

How can we strengthen the protection of our lessons?

Please help.
