Apologies if this has already been posted. I was doing some work in my office when my phone rings. I look and it says my number on the Caller ID. Weird. Picked up and no one's on the line, and the line disconnects. There were some old threads (back 2-3 years ago) about a possible scam from people trying to hack into voicemails. But no real explanation or anything concrete of what's going on. Anyone else experience something like this? Just in case it matters, new iPhone 6 Plus on AT&T.
