I have FIOS Voicemail activated and voicemail on my physical phone as well. When the phone is not in use the voicemail goes to my physical phone. While I am on a call the voicemail goes directly to my FIOS Voicemail without a signal to me on the phone (so I could switch to the incoming call). If the TV is on I do see the incoming caller id for a brief second (not the usual 3 or so seconds) if I happen to be looking at the TV. Reading the User Guide and some questions on this forum has not provided an answer to this specific question. Should I get an audible notification and the chance to take that incoming call? Thank you!
