I take care of these units for a branch of our college.
Recently ( ? past 6 months from reports I got ), one particular
extension is stuck on forwarding all calls to Voicemail.

When you call it through the auto-attendant ( i.e. dial main number,
get greeting, then dial the extension ), it goes to voicemail without ringing the
phone. Dialing it from another extension - same result.

I had the users dial 7100 to clear all forwarding - same result.
I had them dial 790 to clear all station features. Same result.

I am going out there ( it's a few miles away ) on Monday to look at the TVA
programming.

Someone else set up the A/A programming, so I have to review what he did.

Anybody have more suggestions what settings to check?

Thanks,
