Automated calling system - has called school phone # often, according to CID, which on this IP phone shows only incoming number, not name. Recording states that our car warranty has expired and that this is my final courtesy call (ha!). I did manage to reach a salesman with a thick accent and told him that this school number was registered with the federal and state do-not-call lists, and he said he'd add it to his DNC list. We'll see. One more call and he gets reported. The company name was never stated.
