SX2000 Analog Extension rings/fast busy

[Jrme]

I have an analog non-DID extension that rings and then half way through the first ring, the caller gets a fast busy. It can call an internal extension, but it cannot make an outside call. When you dial an outside number, you get a fast busy. It's not a new extension, and this just started happening this morning. The line status is idle. No CORs, COSs, etc. have changed. Any ideas?

Thanks!

Sounds like ring trip on the circuit. A common problem. Can you move the extension to a vacant circuit and perform an ops check.

Thanks for the quick responses! kwbMitel - There aren't any features activated on the extension. Brian - By circuit, do you mean to try moving to another PLID or just to another pair?

Brian's diagnosis is the likely problem. The phone line likely isn't shorted, but there's some problem either with the line (or port on the PBX, aka the PLID - Physical Location ID) that's causing the circuit to become shorted whenever ring voltage is applied. This is either a problem with the phone (try replacing it first) or the circuit between the PBX and the phone location, or it's a problem on the specific port of the line card in the PBX. In 27 years in this business I have see all 3 problems, but the symptoms are the same: ring-then immediate fast busy. As Brian indicated, the technical name for this anomaly is "Ring trip".

Thanks, MitelInMyBlood. Before I could try anything else, the line started working again. Ever see that happen? Odd, but we'll see if the problem recurs.

I would bet on the problem recurring. These things don't usually fix themselves "long term" If I were a betting man I'd bet on the phone being defective. Analog phones have taken a huge downward slide in dependability since the days of Western Electric (aka "Genuine Bell") and hardwired cords.
