Cell Phones on Wi-Fi not connected...

We have staff members that use the Zoom app on their cell phones as their work phones and are connected to our 1 gig Wi-Fi. They are receiving calls but then the app will not connect, and they receive a message "Not connected. Attempting to reconnect..." This is causing a lot of frustrations for our constituents and staff. This is not the same experience on our hard phones or computer app, but the whole company is mixed on how they use Zoom. Anyone else experiencing this?

We had this issue with a specific group that had egress rules on their firewall. I would check to see if your wifi infrastructure has it's own firewall rules and have your wifi/security admin whitelist the IP's using the below URL. Specifically, have them add the IP's from the Firewall Rules for Zoom Phone. Also, this list changes from time to time. Zoom will add new IP's and remove some. You have to stay on top of these or you'll run into this issue over and over again.
