Hi I am having a licensed plan and I am trying to connect the zoom meeting

My requirement is: anyone in organisation can schedule a multiple meeting with other guys and so on.

I am able to create a meeting using :

My friend is computer illiterate. She is the problem in our group. When her audio is turned on, when all the other members of the group speak, all our voices echo and conversation is impossible. The friend does not hear the echo. When she turns her audio off the problem disappears. We have been meeting weekly for 3 years and this problem has only occurred recently. The friend denies any changes to her settings etc. She has reloaded Zoom with out resolving the problem. She has a Chromebook and Hey Google.

I have Zoom (meetings and webinars) well integrated into my website, and integrated into Wordpress and WooCommerce.   It functions fine.   Now I'm trying to set up a Webinar that requires PAID registration for non-subscribers, with a discount for subscribers (making the webinar free for subscribers.)  I can't seem to figure out how to make this work for the life of me.

If I set up a Zoom Webinar on my site, it works great, but anyone with access to that page can join the webinar without registering.  If I "require registration" via Zoom, that doesn't integrate with the WooCommerce product page that where people pay to register.   If I only publish or send out the WooCommerce registration link, then logically, I wouldn't have the integrated Zoom meeting set up, but I would just be sending people a link to join the meeting. 

So confusing. If this makes any sense, I'd love to have your help.
