To use Xfinity Voice service you need a telephone handset and electrical outlets. Inside wiring and jacks are not required for service. Handsets may be connected directly to an Xfinity Wireless Gateway. Inside wiring and jacks can be connected to provide phone service throughout a residence.
Check that your equipment meets the minimum requirements listed in this article.
Note: If you’re using your own modem for Xfinity Voice, you can verify that it works with your service by visiting My Device Info.

The XB9 Xfinity Gateway does not support Xfinity Voice services. Members with Xfinity Voice service must use a different gateway. You can find your Xfinity Gateway model name on the sticker attached to the bottom or back of the device, or digitally through the Xfinity app.
If you received an XB9 Gateway, contact Xfinity to swap the device for a compatible gateway. If you picked up an XB9 Gateway from an Xfinity Retail Store, you can go to the same location to swap the device for a compatible model.
