How to find out line's associated phone number

[Syd Barrett]

I remember years ago being able to dial N11 and being able to hear a
recording announcing the phone number associated with the line I was
trouble-shooting. A friend of mine has a bunch of circuits coming into
his restaurant and I want to know if there is a sequence I can dial to
find out this information if Cavalier Telephone is the vendor in
question? Obviously I know there are other ways to do this (calling
and seeing what pops up on my cell's display) but I'm more curious
than anything else.

You didn't say where you were dialing from. Since the machine that does the
identification could probably be wired to most any number an individual
TelCo wanted to wire it to you could do a lot of guessing.

Here in Verizon territory (formerly part of GTE of the Northwest) I can dial
999 to learn the ten digit number of the line I'm using. Just a few blocks
away, In Qwest territory (formerly part of Pacific Northwest Bell) dialing
that number results in being sent to an intercept recording.

So the number can be real variable - good luck finding it!

That's why I'd use your cell phone's display as you described.

I use MCI's Customer Service number 1-800-444-3333.
