Zoom Phone not connecting on desktop client

[Ruit]

We've been having intermittent connectivity issues with Zoom Phone on the Windows Desktop client.  A popup on the Phone tab says 'Not Connected, Attempt to Reconnect'.  Chat and meetings work fine but no phone.  Usually a log out, then back into the Zoom client resolves it.  Sometimes a reboot is needed.   Network/internet are both stable. Seems to be randomly happening to several people in the office each day.  No firewall changes, etc. have been made.  Zoom support has yet to be able to figure it out.   Any thoughts from the Zoom Community would be appreciated, thanks!

That's part of my issue as well. I get this message on my Zoom app on my cell. I've reached out to the Zoom rep to see how they can help.
