We have gotten calls from many of the numbers Nate listed. Got another one from the 213-455-5269 number on the business phone at 6:30am. Sometimes they call at 2,3,4 in the morning. Thankfully no one is at the office at those hours, but it would be a different story if it were a home! Google voice maybe? Not sure what the person/people are trying to accomplish but we've also been getting a large amount of solicitation calls with an actual person on the line (lot of rude ones actually). So glad my job isn't to waste people's time, sleep well at night!
