Xfinity Comcast - Adding landline without telephone jack

Hello, I'm looking to add landline service.  I already have an analog telephone handset that I'd like to use but my modem doesn't have a telephone jack to hook it into, and my level of the apartment does not appear to have house wiring.  Is it still possible to connect to Xfinity voice without completely replacing the router/modem?

Their Voice home phone service requires a compatible modem, gateway, or eMTA device with phone jacks. See the "Voice/Telephone enabled" devices on https://www.xfinity.com/support/devices and on the "All Compatible Devices" PDF linked near the near the bottom of that page (at the moment it points to https://assets.xfinity.com/assets/dotcom/projects/cix-4997_compatible-devices/2025.03.25 Full List of Compatible Devices.pdf, but this changes from time to time).

An ATA is typically used to allow POTS telephones to work with an VOIP provider. Comcast/Xfinity's home phone service is VOIP between the Voice modem or gateway device in your home and Comcast, but they don't allow customer-owned VOIP devices to access their home phone system directly.
