312-800-8970

New type of scam, attempted twice in a span of 4 days. I got a new call will on my phone and they hung up before the first ring completed (that came from 312-800-8970). Within a minute, I had a voice mail from 901-586-0670 (though there was never a call from that number), telling me to call the number that popped up on my caller ID to talk rates and terms for a 250,000 credit line available to my business. So they call my phone from both lines almost at the same time so that they can leave me a voice mail without having to talk to me (I never answer calls from unknown number so they didn't need to bother with this scheme).
The same thing happened 4 days ago, with the call (ring) coming from 928-233-8269 and the voice mail being left by 307-316-4004.

Call came through as "Scam Likely"  out of Reno Nevada but then my  voicemail showed it from from 312-800-8970 (Chicago, Illinois) stating "they were following up on my business line of credit and I was pre- approved for $250k. Give me a call on the number that pooped up on your caller ID. I'd really like to catch up and go over some rates and terms."

Update- the number that called was 530-479-1298. The voicemail number was 312-800-8970 from the same person.
