Hi,

First, Happy New Year! Second, please excuse my English.

I’m having a major issue installing RingCentral on multiple PCs in my company, and maybe others have seen this before.

On Windows 10 computers, I install ringcentral.exe (not the MSI), and all features work fine (Meetings, Chat, etc.) — except for calling. Calls don’t work in the desktop app but do work through the Chrome extension.

When I try making calls from the web app at app.ringcentral.com, I have the same problem. Even after uninstalling the Windows app and the Chrome extension, the issue remains in the web app.

I don’t receive any error messages — the call starts and then drops after a few seconds.

Here’s what I’ve tested:

• On the same computer and same Windows user account, if I launch Windows 10 Sandbox, calls via app.ringcentral.com work fine with the same RingCentral account, microphone, and speakers.

• If I launch the web app using a different Windows user account, I still have the same problem.

• If I use the same RingCentral user account on a different PC (one that doesn’t have this problem), everything works fine.

The issue occurs on laptops, desktops, AD accounts, local accounts, on a network with a firewall, and even on a home network.

If anyone has any idea what might be going on, I’d really appreciate the help — I’m stuck!

Thanks in advance,
