An unwanted call from this Los Angeles VOIP number arrived today. When the answering machine picked up, there was dead silence, followed by a disconnect. This is the tactic of robocallers (unlawful telemarketers) who continuously troll the phone lines, desperately seeking gullible schmucks to victimize. Trolls like these are why you should always LET YOUR ANSWERING MACHINE TAKE THEIR PATHETIC CALLS.
