Q: Can I keep my current phone number?
A: Yes, you can keep your existing phone number and receive Comcast Digital Voice service. This means you can continue to receive calls from your family and friends without having to notify them of a new telephone number. (We do need to verify portability with each phone number - if you are moving to a new area, you may not be able to keep your old number).
Q: Will Comcast Digital Voice customers need to purchase additional phones or equipment?
A: Customers with touch tone phones will not need to purchase new equipment. The customer's existing telephone wires and phones will work with Comcast Digital Voice Service. There is some equipment that needs to be installed, but the customer is not responsible for purchasing or leasing the equipment. Comcast Digital Voice service will not work with rotary phones.
Q: What is Voice over Internet Protocol (VoIP)?
A: Voice over Internet Protocol (VoIP) is a technology used to transmit voice and related calls over a data network. Most VoIP service providers use the public Internet to transmit your calls, but Comcast calls are transmitted over our private advanced broadband network. Using broadband technology, Comcast Digital Voice service is able to provide you with a number of enhanced new innovations, without sacrificing any of your current phone features or the call clarity you expect.
Q: What if my electricity goes out? Will I still be able to use my Comcast Digital Voice service?
A: The eMTA (embedded Mulitmedia Terminal Adapter) Comcast supplies with your Comcast Digital Voice service contains a backup battery designed to power the eMTA for several hours of continuous service. The actual length of battery backup time will depend on the amount of time you use the phone to place outgoing calls during a power outage.
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: What equipment is needed for my Comcast Digital Voice service?
A: For Comcast Digital Voice service to work, and eMTA (embedded Mulitmedia Terminal Adapter) is installed to support your Comcast Digital Voice service.

Q: Does Comcast Digital Voice work the same way as traditional phone service?
A: Inside the customer's home, the only difference is that Comcast Digital Voice does not work with rotary phones. Outside the customer's home we take advantage of state of the art broadband technology and, in most areas, VoIP (Voice over Internet Protocol) technology. This allows us to deliver crystal clear calls and advanced calling features.
Q: Can I use other services (watch cable TV, surf the Internet) while using Comcast Digital Voice services?
A: Of course! Thanks to the power of broadband technology, Comcast can provide a whole range of products supplied through the same coaxial cable, without interfering with TV viewing or web surfing.
Q: Are Comcast Digital Voice calls routed across the Internet?

Q: Is the sound quality clear with Comcast Digital Voice?
A: You bet! Our digital communications network transmits a "clean" signal with less noise and distortion than many analog networks. Noise is essentially screened out of the signal so you get crisp, clear sound.
