Really weird ... I had a call that went to VM, when I tried to retrieve it, I got a dial tone, dialed *99 and then the phone went dead. Then, in trying to make a phone call, again I had a dial tone, dialed the # and it went dead again. I got my 2nd phone and called the main phone, it rang after a long delay, but kept ringing and never went to VM. I see other msgs about dropped calls, but I have a dial tone ... all seems fine until after the # is dialed ... can't even check VM from my phone. This just started within the last hour. I can't call Comcast and I can't get on chat.
