This is interesting...I was home to hear the phone ring once but nothing came up on caller ID. That was it. I checked my call logs via my provider's website and it showed this number had called at 11:25 a.m. I am definitely glad that it didn't come through further but I am surprised that it didn't even register on my phone itself after the call was cut off. I have run out of available slots through my phone company to block numbers, but somehow this one was stopped in its tracks.
