I believe this is a canvasser that also has several other numbers so must be using an app that gives fake numbers. It does say Alta CA on caller ID which ends up coming through even to those who try to block calls because it does give caller ID info. This call was the same as a person below states talking about abortion. Same person calls with a 213-457-3803 number. Call both. It has the same voice recording to leave a message. This person must stay at home all day with nothing else better to do than to call certain numbers EVERY single day. Poor sick soul....
