This is cute, really cute. Someone has a sense of humor, caller ID comes up BEDROCK. Second CA call I've gotten in the last two days. No message. Telemarketer or scam, judging from past comments floating around.
Typical robo-dial/SCAMMER call pattern - land line rings, caller ID shows "Burlingame CA", do not recognize, do not answer, rolls over to voice mail, no message left = SCAMMER = BLOCKED ! ! !
