We've noticed this number will do a partial ring, hang up, and ring back. If you don't let the phone ring one whole ring, caller-id doesn't work. That said, when I did pick up, the Indian sounding individual asked me about medical information, very personal medical info. I told him never to call back and remove me as I'm on federal do-not-call.
He proceeded to tell me he'd keep calling back over and over. Then, he launched into a barely intelligible rant about sex, dogs, and blood. Couldn't make out most of it.
Upgrading to Ooma plus so I can block these scumbags.
