Identifying a Phone Number on a line?


Jul 30, 2004
A little out of topic, but it is kinda networking...

I've got about 20 lines coming into my telco closet from Verizon (VZ). They aren't labeled, and now i'm trying to identify which line is which phone number. I was once told of a phone number Telecom techs could use to dial that would then tell you what phone number was on that line. I knew that number up until about two months ago when i forgot it. Now, i could really use it again. Does anyone happen to know that number?

I know i could just call my cell from each line to get the number, but that takes a lot longer than just dialing that identity number.
