What channel is the voice on if you have xfinity?

Xfinity does not have its own channel dedicated to voice communication. Instead, it provides voice service through its Xfinity Voice product, which operates over an internet connection and uses Voice over IP (VoIP) technology. With Xfinity Voice, customers can make and receive phone calls using a traditional telephone or a compatible VoIP phone. The voice service is available as an add-on to Xfinity's internet packages and can be accessed through a dedicated phone number assigned by Xfinity.
