Q: If the cable goes out, will my phone go out too?

A: No. Comcast uses the power of broadband to deliver Comcast Digital Voice, cable television, and High-Speed Internet services to our customers over a single coaxial cable. To ensure reliability, these services function independently of each other, so if one Comcast service is affected, it does not necessarily mean your other Comcast services will be affected. But is a storm or accident knocks out our network, then muliple services may be affected.

Q: Are Comcast Digital Voice calls routed across the Internet?

A: No! Comcast keeps the calls on their private broadband network until our switch delivers the call on the PSTN (public switched telephone network).
