So in this lot of telecom scrap I got the other day, came boxes of new and older office phones, and on eBay lots of 10+ sell for hundreds of dollars. Tried hookin them up to my home phone line but I almost knew from the start that they wouldn't work on that... Are there any other ways to test them? The ones at our shop that look like these ones are only run off a residential line... Tried google and couldn't find much of anything... Any ideas?



Selling as untested would yield much less I'm sure and would love to say they work.
