Got a call from this number just now. I was expecting a call so I answered, which I usually do not do if I do not recognize the number. There was dead silence on the other end and then a hang up. They did not say anything, so I have no idea who it was or what they wanted.
I get several calls from this solar company every month. They use different numbers with the same area code. I use a free app, Mr Number, to block calls like this but I only have a cell phone, not a landline.
