Cisco VOIP phone 7962 w/ Xfinity Voice

[Findit]

Hello,  I have a Cisco VOIP phone.  Is there anyway to point that phone to use Xfinity phone?  I have Xfinity Voice on my exiting copper line.  Knowing that Xfinity is VOIP can I point the Cisco phone (I have Poe) to Xfinitys VOIP and login using the Cisco phone?

Their home phone service is VOIP between the Internet/Wifi/Voice gateway device in your home and Comcast, but the phone jacks on that device provide only a POTS (analog "Plain Old Telephone Service") interface to customer touch-tone telephones. Their equipment may also work with CAT-iq 2.0 Cordless phones. But they don't allow customer IP phones to access their home phone system directly.

AFAICT the 7962 is not compatible with a POTS line or with CAT-iq 2.0.
