If you have Comcast Triple Play or Xfinity Voice, then you must buy an approved voice modem with a phone jack such as the ARRIS SVG2482AC or Netgear C7100v Nighthawk. Or the Netgear CM500v if you plan on using a separate router. If you have Xfinity Triple Play, there is no way around buying a compatible voice modem. Sure it may cost more up front, but it will still save you money in the long run because you will no longer be paying the $10 a month rental fees. It will also provide you with the newer technology and more advanced higher performing wifi cable modem with a phone jack and a built-in wireless router. The good thing is, the Netgear C7100v is a combo modem router, meaning you do not have to purchase a separate wireless router, you get both in one device. A high speed 24 downstream channel DOCSIS 3.0 EMTA voice modem, and a powerful wireless gateway for Comcast Xfinity Triple Play Internet. It is much better than the ARRIS SVG2482AC, but we have an even better Xfinity voice modem for most of you.

You will need your own router
You’ll note that the CM500v voice modem paired with this Netgear AC1750 router is a much better deal than the C7100v combo voice. We highly suggest this pair if you have Comcast speeds of 200Mbps or less. If you have more than 200Mbps, you need the C7100v no matter what. Note that the C7100v modem is not approved for speeds over 500Mbps.
Not only does this stand alone pair save you money and provide the best option for speeds up to 200Mbps, it allows you to chose a much stronger separate router if you have a large house. This is very important to many living situations.
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 Xfinity Triple Play– whether you use it or not– you need the voice modem with a phone jack. I have had readers also report that they tried and Comcast would not let them use a normal DOCSIS 3.0 approved cable modem.
Is this my only option?
If you have Comcast Voice Triple Play, then yes. You must use one of the two telephony compatible voice modems. Your options are very limited, but the Netgear C7100v is a solid DOCSIS 3.0 EMTA modem, meaning it is fast enough for Comcast packages all the way up to Extreme, Comcast Blast, and Performance. Get the best internet speeds Comcast has to offer, and they have a built-in Wireless AC router. Which one would we recommend? The Netgear C7100V no doubt. See the differences below in the comparison chart.
Arris SVG2482AC vs Netgear C7100V Review
In any given situation I would pick the Netgear C7100V over the Arris SVG2482AC. The C7100v has a Broadcom chip while the ARRIS SVG2482AC has the flawed Puma 6 chip and is on the list of bad modems. This is pretty big because even after they released a firmware update, users are still reporting latency spikes and internet slowdowns. Making the very popular ARRIS voice modem, not an option.
But even if the ARRIS SVG2482AC did not have a bad Puma 6 chip, it would lose this battle for many reason. One, the Netgear C7100v is a faster combo modem/router, it has built-in USB ports for network storage, and the battle-tested Netgear GUI and firmware. Yes, the ARRIS SVG2482AC voice modem may have two physical USB ports on the back of the modem, but they are not for your use. They are for service technicians and will not host an external hard drive or printer. The firmware just isn’t supporting it. I consider this a huge flaw. They make no claims of the device even having USB ports in any of their marketing, yet you can see they are there for service techs. This is the sole reason why I would get the Netgear C7100V. I love my network storage and back up. Rest easy, never lose a photo or document.
The USB ports are not the only enhancement with the Netgear C7100V. As you can see it has a slightly higher wireless throughput, which may be pretty unnoticeable if at all noticeable so do not let your decision ride on that. If you’ve ever owned a Netgear Nighthawk router before, you’ll be familiar with the Nighthawk built-in software, and I do prefer it over Arris’s GUI. That’s pretty much the consensus with most people in tech. So when it comes down to the higher cost you have to ask yourself, do you need USB ports, want a better GUI / firmware and care about a small speed increase that you can’t even notice unless you’re transferring large files over your local network? For me, the answer is yes.
- Broadcom Chip
- USB Ports
- Faster Wireless
- Better GUI
- It’s Netgear
- Puma 6 Chip
- No USB Ports
- Slower Wireless
- ARRIS GUI

Netgear CM500V Vs TM822R Comcast Voice Modem
You’ll note that these modems are a lot cheaper. That is because they are not a combo router and they are solely a stand-alone voice phone modem to be used with Comcast Xfinity Triple Play. This is great for me because I prefer to use my own router. But what is the difference between the CM500v and the TM822R? Speed, age, technology. The TM822R is much older and only has 8 download channels where the CM500V has 16 download channels, yes double the bandwidth. Because they are essentially the same price, it is always suggested that you get the Netgear CM500V phone modem with your own router. Preferably anything wireless AC1750 and above. These voice modes are fully approved, and compatible with Comcast Xfinity Voice Triple Play packages and have built-in phone jacks.

Comcast Modem With Phone Jack for Xfinity Voice Conclusion
The obvious conclusion if your heart is set on a combo modem router, get the Netgear C7100v Xfinity voice modem for Comcast. It is undoubtedly the winner between it and the ARRIS SVG2482AC. No competition when it comes to EMTA modems.
If you want to use a separate router as I suggest, then get the standalone Netgear CM500v voice modem and a cheaper or stronger wireless router of your choice. But nothing below AC1750.
