I'm on a time crunch to complete the Zoom Phone setup for my organization by the end of the day and need help resolving.  Could someone please help me at your earliest convenience?

I moved my phone system over to zoom last year and have not had any issues for the most part until here recently. I literally cannot function my business with how God awful terrible the phone reception is.  I have two different Internet providers just for this purpose and I am encountering the same terrible phone issues with both Internet providers as the phone constantly cuts out. I thought at first it was my wireless headphones, which were Apple pro headphones with my brand new MacBook Pro and I purchased a brand new wired headset, but I am still encountering call quality that makes me repeat myself 1000 times before the other person can understand what I'm saying.  I literally cannot function my business with your phone system, and I am beside myself upset and downright pissed off as moving phone carriers is not an easy task.  I don't know what to do I have tried everything and what's worse is I can't even call you to discuss this. I am sick and beyond belief.

I'm seeking advice for a large room audio setup where a conference table is serviced with a (Bluetooth) omnidirectional speakerphone-puck, and a handheld wireless/BT mic can be passed around up to 30'/10m . Ideally, the speakerphone and handheld mics are daisychained, reduces noise, and eliminates feedback - just works. Thanks.

My Zoom app works with and without my VPN being active.  I can join meetings, do internal calls as a meeting, and if my VPN is off make phone calls using the zoom app.  Once I turn on my VPN to connect to my work  computer I no longer can dial or receive calls using my zoom number.

Zoom ported my business number today but system is down. Cannot receive or send calls. A support ticket was submitted but still down 2 hrs later. Have had to cancel the rest of my business day as a result. Why is no one contacting me to resolve this issue? All articles in support do not address what happens when the system goes down.
