Yeah, that's EXACTLY what it's doing. I had no idea that was happening at first. I was on the other side of the house, and I saw my phone light up as if it had just answered a call, except when I (gingerly) said hello, there was nothing. But when I walked into my kitchen where my computer was, having re-dialed the number that had called (and hearing no ringtone ... just seeing that I was on the call), I heard the voice coming out of my computer! And when I 'talked to it' (is anyone watching me do this, I wondered??), they heard me and we had a conversation!! Until i rebooted my computer, the same thing continued to happen. And it did it again today!! Had to shut my computer off to make a call. But right now, it's fine! IS THAT NOT CRAZY??? Any ideas??
And, I am signed into google email quite often, but I don't have google voice. I DO have skype, but it wasn't on when this was happening. And I checked the applications/processes running with task manager and didn't see anything suspicious.
