Shown on caller ID as Toll-free call
Called on a Saturday morning at 1:15 AM  and again 1:40 AM.
Online research turned up a couple of nuggets on different sites:
Landline registered under KRISTINA LITNER, Otter Pond Rd, Bridgton, Maine

I picked up the 2nd time.  Silence - seemed like there was a person on the other end. I said, "I know your name and where you live.  Don't ever call this number again."  I blocked the number.  Immediately afterward, another call at 1:47 AM from 800-282-5129.  No message left. Coincidence? I think not.

I will cross-post this info to the second number that called me.

D. I got the same two numbers that called me in a row, within a few minutes of eachother, as well as one from 972-929-9540

you gave them what they wanted they call to see if it is a valid number then they sell your number. I doubt it was a person they have Robocall programs that cycle numbers to establish if the number is owned by a real person.They sell the numbers to Telemarketing companies. I suggest you not answer calls like this since you don't know the true reason for the call. They call at the wee hours because they know it is likely more people will answer I mean after all it is hard to not answer in case it is an emergency right? They called me twice this am once at 1:15 and again at 1:45.
