Just got a call from 323-795-4268 on my cell 5:15 pm on 3/21/16. I suspected telemarketers, so didn't pick up. Turned out I was right, it was a "Home Services" telemarketer, which left a pre-recorded message on my voicemail for a "free consultation" re: roof, windows, insulation, tankless water heaters, interior or exterior paint, etc.
Received the call - we NEVER answer unknown telephone calls anymore - we BLOCK them!
Check Amazon for call blocking devices or blocking phones - we have and use both!
