Being it was a local number I answered.  Took several seconds to hear someone on the other end, knew then it was a salesman.
He claimed to be with AT&T, he asked to speak with the person responsible for our phone bill I told him they were out of the office but to give me  his name and return number and I would have them call him in about 15 minutes, he said sure you can.... and hung up on me.  This 'person' is now programmed in my phone so I will know who to hang up on next time.
