Just received one call after the other, on our land line, from this number. Caller ID: Miracle Ear. With each call, I just picked up the phone and didn't say anything. I held the mouth piece away from my mouth so the caller couldn't even hear a breathing noise. A female on the other end said "Hello" twice and then hung up. I hope she has marked our phone number as "no response" and takes it off their calling list. I suspect the 2nd call was just the marketer trying the number again to make she she had it right. The 636 area code is a local number for us (St. Louis, MO area and surrounding counties.)
