If you have Comcast Triple Play or Xfinity Voice, then you must buy a voice modem. There is no way around it. Sure it may cost more up front but it will still save you money in the long run and provide you with the new technology and more advanced higher performing equipment. The good thing is both of these combo modem options are future proofed modem routers so you do not have to buy a separate router at a higher expense. You get both in one device. A high speed 24 downstream channel DOCSIS 3.0 modem, and a powerful wireless ac router.

Arris SVG2482AC Cheaper Voice Modem.
Netgear C7100V Best Voice Modem.
Older cheap modems have been End of Lifed.
What if I am not using the voice line? Do I still need a voice modem?
Yes, you do. I called Comcast myself and the bottom line is if you have Triple Play– whether you use it or not– you need the voice modem. I have had readers also report that they tried and Comcast would not let them use a normal DOCSIS 3.0 approved non voice modem.
Is this my only option?
If you have Comcast Voice Triple Play then yes, you must use one of the 2 the telephony modems above. Your options are very limited but these are both brand new future proofed 1Gbps modems, meaning they are very fast with built in Wireless AC. What one would I get personally? The Netgear no doubt. See the differences below.
Arris SVG2482AC vs Netgear C7100V
In any given situation I would pick the Netgear over the Arris because it is a faster combo modem / router, it has built in USB ports for network storage, and the battle tested Netgear GUI and firmware.
