Hang up call.  ID showed Cell Phone CA.  Another web site had this info:  Spoofed Numbers: Caution, 858-624-4881 is a "spoofed" number, which means that whoever called you "tricked" your caller ID to display an incorrect phone number. Telemarketers do this so you cannot complain, but they failed... you can still file a complaint here to fight back against unethical telemarketers.
