... C7100v ...

The C7100v is still listed as a compatible device. For other compatible retail devices, follow the "See all modems" link near the bottom of https://www.xfinity.com/support/internet/customerowned, and then under the "All compatible modems by brand" heading click each brand and review the devices. For a Wifi gateway with phone ports you'll want to choose a device that is listed as "Built-in WiFi: Yes" and "Voice-enabled: Yes". There aren't very many. 

Using devices on Internet speed tiers for which they are not compatible with tends to produce unexpected results, often speeds well below the ones you are paying for, so you'll want to pick a device with its "Wired download speed" at least as high as the your Internet speed tier. You might want to go a bit higher to allow for Comcast/Xfinity's occasional tier speed increases.
