Received a phone call from this number today.
I did not answer the phone, and they did not leave a message on my answering machine.
My caller ID reads this phone number as "California."

Everyone be cautious ... more than likely, this is a robocall attempt from telemarketing scammers.
Also, they may have "spoofed" this number.

Bozo is now blocked.

Received a call from this number on a Sunday morning. We didn't answer and it left a ridiculously long message with elevator music playing. As if they called and put us on hold. Ridiculous.

An unwanted call from this unspecified (possibly spoofed) CA landline number arrived today.  When the answering machine picked up, the caller left no message, just dead space.  Robocallers (unlawful telemarketers) do this all the time while trolling the phone lines seeking gullible schmucks to victimize.

DO NOT BECOME A VICTIM OF THESE TELECRIMINALS.  LET YOUR ANSWERING MACHINE TAKE THEIR PATHETIC CALLS.
