I hung around for an hour and a half and it never kicjed on , they had a voicemail that was recieved after hours and you could here the hum/wine , I don't think that it is the air compressor, it shouldn't kick on when it is not in use.

I agree with both statements. Just to satisfy them all you have to do is open a blow gun (or whatever dentists call those things) and the compressor should kick on. Keep in mind also that there should also be a vacuum pump for the spit suckers. Works the same way- turn something on.

Here is a small one that drove me crazy once. Almost the same thing was being complained about...it turned out to be that on the opposite side of the wall in the next suite, a dentists office, was there X-ray equipment on the wall. Everytime they took a picture it would cause RF or EMI and the our customers KSU would glitch. some times calls would drop but mostly the calls in progress would here a white noise that quickly got louder and then as quickly went away. It took us a while to figure this out, we changed KSU's, ran new grounds, had electrician in.
Air compressors will lose air overnight and recycle some of the times so its not uncommon for a air compressor to kick on at odd times.
We also had a building issue in a strip style office park where the huge on the ground transformer just outside the customers back door was causing power issues for several customers. They came out and repaired something and everything was fine. The electrician discovered this one. Also a machine shop's electric welder caused problems once that was solved by using shielded cable for the shop phone.

Another thing you might double check--is the noise REALLY on all lines, or as is customary, the customer pays no attention to when the noise occurrs and just tags the complaint to 'all the lines' when only one is actually affected.

We had to move the system and backboard to another wall. We extended the lines and house cables on a couple of 25 pairs with no problem and never had a reoccurance. The issue was the KSU's motherboard or processor and not the cabling bringing the EMI/RF into the system. It was that they were in fact ...back to back.
