Called me just a min ago and left no voicemail. Going to block it!

Caller ID: UNKNOWN NUMBER  Machine answered and usual "Public Utility Commission" solar recording came on.  They keep changing their number to circumvent our blockers.

Answered call. No response. Only silence. Threatening or terrorist related

this number started calling last week.  hangs up when it reaches our machine...which it always will since we can't answer our phone any mre thanks to these idiots.
in 2015 this was the # for the "share program" in riverside co.  it still says "riverside county" on the id, but i'm guessing it's spoofed.
