I got a call from this number as well. I missed the call, but called them back and it went straight to a voicemail message for a Joanne Frankforter. As far as I've found, she's a solicitor and I left a message asking her to take me off her call list!
I work for a small county in Northern California and get a call from this number pretty much every day. I usually let it go to voicemail....but it is still annoying!
