I am a new customer and trying to figure out whether I have FIOS voice or FIOS digital voice. As I recall, the installer said I had FIOS digital voice. I had FOIS triple play installed. To install the new phone service, the installer simply disconnected the phone from the POTS box outside and ran it over to the ONT and reconnected. The phones seem to work as before. The FIOS guide says that caller ID on the TV is available, but it doesn't work. The guide also says that FIOS digital voice is not available. As I recall from searching the internet, FIOS digital voice was a very expensive and unique service that called for the installation of new phone jacks. However, the advertisements for triple play indicate that FIOS digital voice is part of the package at a much cheaper price.
One reason, I don't know much about what I have ordered is that I mistakenly succumbed to a door to door salesman and can't interpret what little paperwork he provided. I also have no idea what the monthly price will be. He gave me an overall price for the package verbally but it cannot be confirmed by anyone at Verizon. In any case, hopefully, I will be able to view the bill online soon and maybe know that. My online account has info on the FIOS package but nothing to indicate which phone service I have.
By the way, it is a myth that Comcast service is worst that Verizon. Each company has may customers and much equipment; so problems are inevitable. However, the ability of one company's CSRs to solve your problems is no better from one company to the next. This is what makes forums such a this so valuable.
