Today we switched from our old desk phones to the RingCentral application for incoming and outgoing calls. Outgoing calls works just fine, but nothing is ringing for incoming calls. All our incoming calls are going unanswered. After the call disconnects, we get an alert that we missed a call. All settings are correct for display incoming call (turned on).

When I check the status of each user phone, they are all with a red x, and states offline. I did notice one employee had his computer verified and his works fine, but I don't know where to go to verify computer.

I have been on hold with customer support for over 2 hours with no answer.
