Not sure quite what I did, but suddenly if I dial another person’s extension, it not only doesn’t display their name, but doesn’t show me if they are on another call. Help! 
Hi
Sorry that we missed your question! But if you still need help, here's the suggested troubleshooting guide that you can follow;
Restart Your Phone or App
Turn off your phone, wait for a few seconds, and turn it back on. This can help reset its connection to the network and clear minor glitches. If using the app, try to log out and log back in.
Test with Other Extensions
Try dialing different extensions to see if the issue persists across all calls or is isolated to certain ones. This can help pinpoint if the problem is with your phone or app specifically or with the office phone system as a whole.
If the issue is still the same, please send a ticket to Tech Support at https://support.ringcentral.com/new-case.html.
