My office receives several calls per week from 217-481-8314. The Caller ID reads "GET CASH NOW" but there is never anyone on the other end of the line after I answer/introduce myself.
Called again, this time CID said "Springfield IL" so I picked up received and immediately hung it up again. We get nothing but spam/scam calls from IL (we're halfway across the country) so they all get hung up on.
Called again - their call was blocked and our phones did not ring - we have the 312 and the 217 area codes blocked.
Earlier today, we also received a call from 312 (Chicago area code) 792-3457.
Don't know if these calls are related.
