Cannot use either the Desktop or Web-based app with RingCentral for inbound/outbound calling

@Ben Kohns Thanks for reaching out. This is unusual - and not something our team is hearing about from other users.
Can you or your IT Admin create a case with our Support team?
If it is indeed a singular issue, they can help troubleshoot. If it's a bug, they may already be working on the issue and your feedback about the issue will be helpful.
You can create a case HERE.

Hello, @Ben Kohns! Apologies for the inconvenience. We would highly suggest opening a case HERE. Our phone support will reach you as soon as they get your request. You can also check our support site https://support.ringcentral.com/?language=en_US.. Thank you!
