The caller ID 951-491-8810 shows on my TV screen but then gets posted to my UVerse call log as "Private".  Has done this twice.  They don't leave a message.  Have now blocked it.

Constantly calls. Robo dialers I thought were illegal. They must be scammers.  I advise you not to answer.

This company calls my work number at least four times a month.  Bottom feeder debt collection agency, trying to locate someone who had my work number.  I answer, "(Name of my company), this is Thom" and they consistently ask is this is Mike Drummond.  Why would I say my name and they ask if I'm Mike?   When I try to explain that I'm not Mike and to stop calling me, they act like THEY'RE the one inconvenienced and hang up.  Idiots, stuck in a dead-end, go nowhere job.

Didn't answer when they called.  Called the number back from another phone.  The line was completely quiet but eventually a guy answered as Horizon Power.

They called again !
I did not answer the phone, and they did not leave a message on my answering machine.
