it's been several years since I last installed a multi-line system. I used to have a list of 800 and 877 numbers I could call that would read back the phone number of the line I was calling from. I can't find the list and have been called in from semi-retirement to install a simple AT&T 1080/1070 4 line system. I need help in identifying the numbers at the interface. Can someone help me. I work for Coast Electronics in Morro Bay, Ca. 805-772-1265. My supervisors are John Weiss (owner) and Jon (Woody) Wordsworth.

You can always call your cell from each line to get the number.

EDIT: Sorry we don't post those in the open forums. Thanks.

I agree with Dave, if this a New Install, The Service Provider will Have The Numbers Marked at the Dmarc. If Your Changing out an Old System, Just Look at The way the Lines are Feeding into the Exsisting System and Swing them over to Your New System.

thanks guys, yeah the cell phone thing, should have figured that out myself. like I said, it's been a while since I was on the install side of things.
