Received a similar call from another 217 number. In my case it was Laura from some Warranty services asking the same question: "Can you hear me clearly?". I hung up after listening her question. For some reason this scumbags are looking to have a recorded "Yes" for some sort of scam. I made the mistake of answering that call and now I have calls from this area code twice a day.
Just received a call from this number. St. Joseph IL popped up on the ID. Probably some lowly spammer and coward for not leaving a voice mail. Get a life whoever you are.
