Hey Judy,
I understand what you are trying to do and your approach is exactly how I would handle it.

You are going to have to scan for everything the DN that you don't want ring is programmed into. Any ring group, DRT etc.

Your post says you got a phone call and you checked programming. Did you simulate the problem and see it for yourself? Was it a button ringing or an I/C path? Are these POTS or PRI lines?
