Sorry to say but, there isn't anything I know of.

Sorry Phone-guy, but the answer is nope.

Analog phones are pretty vanilla and the lines don't care if anything is plugged into them. They'll keep working nonetheless.

what you could do is verify all the analog lines that you can by going around writing down the analog extensions .Then disable the ones you could not find.Expect to get a few calls on this? like my modems not working ,or a fax line or a phone.
Wait a couple of weeks then out the disabled ports that you never got a call on.

You could always try calling the DNs and see if anyone answers.

Well, Since I can't do a status of them, I suspect I'll end up just tracking the Few "Mystery" ones Done through a Number of Phone Rooms, to see what if anything they are connected to, If they aren't I connected to anything I will just "Out" them and worst case as time permits, check the station wire in the ceilings with a Step ladder,Flashlight, a toner & wand

This topic was posted a while back and I spoke of an old school way..

Take an Ohm meter and check for the ringing circuit of a 2500 or 2554 type set.

The ringing circuit places resistance across the TN (around 1K resistance) whereas a TN without a phone connected would be completely open (The circuit isn't complete).

Let me see if I can find that post....

Okay Chas you got me curious now. Where do you get all these pictures from? Or do you make them yourself?
I’ve seen you pull quite a few helpful pictures out of a hat in the past few months.
