Connecting a Yealink SIP T54W to my Xfinity router/modum

I have Xfinity triple play. Right now I use an analog phone with my Xfinity land line phone number. I just bought a Yealink T54W VOIP phone and would like to connect it to my router and use my Xfinity telephone number on the new Yealink VOIP phone. It says "No Service" on the phone. It is WIFI Yealink phone and my iPhone connects perfectly through wireless. How can I get my YeaLink to work with my Xfinity phone number through my router?

... How can I get my YeaLink to work with my Xfinity phone number through my router?

Their home phone service is VOIP between the Voice modem ("modem": short for "modulator/demodulator") or gateway device in your home and Comcast, but the phone jacks on that device provide a POTS (analog "Plain Old Telephone Service") interface to touch-tone wireline telephones. They don't allow customer VOIP phones to access their home phone system directly. A VOIP handset would only work with their Voice home phone service if that handset also had a POTS interface and was connected to one of the RJ-11 jacks, or to a base unit connected to one of them.

To use a Wifi or Ethernet connected VOIP handset you'd need to subscribe to a service that provides access for such devices. Comcast residential does not.

@BruceW Thank You. My old analog V-Tech worked but did not give me the features that the Yealink gives. I purchase a short cable adapter (RJ-11 to RJ45) and plugged in back of my modem/router and the same wall jack that I had my old V-tech analog plugged into and it still did not worked.

So should I abandon the ideal of using a VOIP phone unless I did away with Xfinity or used another service such as Ooma, Vonage, etc with Xfinity?

As sated above, to use a Wifi or Ethernet connected VOIP handset you'd need to subscribe to a service that provides access for such devices. Comcast residential does not.
