Can I buy a telephone that indicates that I have a voicemail message on fios without having to pick up the phone and listen to the dial tone? For example is there a phone that will blink a light when I have voiemail?
Yes. By default the feature is not turned on and you need to call up Verizon to enable it. One of the voicemail manuals calls it "Visual Message Waiting Indicator / FSK". It also lists this number (1 800 483 1000) to call to have it setup.
Actually the default is Audio and visual, the only reason other than requesting just one is the rep clicked on the wrong option. Also u can use VZ call assist that will help you also if your close to a PC.
