If the extension is programmed here it will ring with no one on the Line!
This is an old feature to check trunks.
I've seen this happen in the past.
Hope this is it.

Automatic Circuit Assurance is NOT enabled. Thank you for the information and possible problem though.

Does it happen enought to do a list trace on the station and capture it?

If it's a 8410D, is anything coming up on the display when it rings?

Is this just a regular extension or is an agent logging into it?

Does it just happen when the phone is on hook or after a call is made?

Not enough to do a trace on it. It is at one of my other buildings. Nope, nothing showing up in display when it rings. Just a regular extension of my Definity PBX. Happens when on hook, after a call is made, has no affect. I am told, they hear it ringing in a print room, they go in and answer it...nobody there. It is not a phone used everyday, so I just have if off hook for time being...trying to find the root cause. Happens maybe 3-4 times a day or so.

Execute the command: list usage extension xxxxx

Is it being used in a hunt group, call answer group?

Execute the command: list call-forward

Is it listed as a call forward point?

Hardware Platform? Definity / CM software version?

If you have call accounting, put the station in intra-switch-cdr.
MST trace will tell you.
If load supports "go tcm" you can see previous call records from there.

A great teacher, does not provide answers, but methods to teach others "How and where to find the answers"
Avaya. Too little or no help? Expensive?
For FAST switch support at bargain rates, give bsh a call.
