Just received a call from this number. No name on caller ID. No one answered from other end. Listed as originating from "South San Francisco Bay Area", but it is a 408 number, which is a South Bay area code, not North. I note that in the last few weeks, I have had solar companies calling my cell phone a couple of times a week. Not sure if this is related, but note the previous posters's remarks.
I've received repeated calls from this and other 408 numbers that show up originating from Morgan Hill and Gilroy. Normally, there's no one on other end of phone. The last time they called a person was on other end. I told her to take me off their list! I'm still getting them like 1-2 times week.
