Got a call from this number on 9/8/15 about 5:40.  Of course, the line is silent when I answer until they realize they've got a "fish" on the line, and then they state my name, and a pleasant enough man says he's Dave with some solar company, at which time I tell Dave in my most menacing voice, "I'm not interested and don't you dare ever call me again."  And this pleasant guy just clicks me off as easily as he clicked me on!  Imagine that.

Thank you for the info. I just got a call from this #. It hanged up as soon I answered the call. The caller ID showed as San Diego Count....

Called at 7:50PM PDT 14Sept2015 CID=San Diego Count which doesn't mean much to me so I don't answer and they don't leave a message. Can't be important as I am on the Nat'l Do Not Call List and if they dis me I naturally dis them, simple as that. I am grateful to those who take the time to answer and post informational comments.

No one on the other line. Will block if called again

The caller, SAN DIEGO COUNT ( displayed as ID on our phone. ) called us @18:43. FTC suggests us not to answer unwanted call on the.spot. I returned the call hiding my number few minutes later, a lady message: ... not for this service." Then hung up on me. 2nd time a lady message let me leave message. So I left a  a " Do not call again " message. I just learned how to block unwanted phone/ It allowed me to block up to 20 number, this is the last one I blocked.
