Standout Features

Xfinity voice is part of Comcast’s family of products, and as a result has some of the best voice clarity of any VoIP service. Because the company has its own separate lines purely for VoIP, there won’t be a slowdown on your internet service while using the phones. Clarity and speed should be expected to only improve as the company converts to fiber optic cables. The high-clarity service can be linked to mobile devices by way of the app, meaning that VoIP calls can be placed and voice mail can be accessed even if you are far away from the hardware at your home or office. The service comes with a package of standard features that take a lot of the headaches out of having a phone line (anonymous solicitors, for one) and are also well-suited for residential users, who can combine the service with other Comcast offerings as part of an affordable package deal.

Ease of setup and management

Users can set up Xfinity voice by themselves, with the assistance of an easy to follow YouTube video. After ordering the wireless modem “gateway” from Comcast, you set it up in a central location in your house near where you will be using the internet.

The modem is delivered with two coax cables, a power cord, Ethernet cable, and a cable splitter. To install, first screw a coax cable into the cable outlet and the other end into the back of the wireless modem, then insert the power cable into the modem and then the power outlet. After the power cable is inserted the modem will begin booting up, which should take about 20 minutes.

You then plug the telephone cable into the back of the modem and wait until the “online” light stops blinking and becomes solid. Boot up your laptop, computer, or other device and find the network name that matches the label on your gateway and then use the password which is listed on the back of the modem.

You then go online to activate your account with Xfinity and at any time you can call a toll free number to automatically activate it. At any time, Xfinity customer service are available to help in the installation process.

About Xfinity Voice

Comcast Xfinity Voice Unlimited is a VoIP (voice over Internet provider) service that harnesses the resources of the massive telecommunications corporation to provide phone service through users’ internet connection. They offer a host of services, including a mobile app that allows users to use and manage their account remotely.

Xfinity Voice provides a budget package (saver) with a bare number of features suitable for someone just looking to make calls by internet from home, and a more expensive option with a host of available features. Both plans provide unlimited domestic calls, though only the expanded plan includes free international calls (though only to a small group of countries).


Xfinity voice limited is a solid VoIP provider that can be counted on to supply top of the notch voice quality and clarity, along with great customer service.

The service seems more geared towards residential users, and less towards large companies looking to get a series of phones linked to an online connection for VoIP calls. Their price is rather high compared to other industry rivals, though for a simple residential user who mainly makes domestic calls, the saver package still comes equipped with some important features and should get the job done.

The service is best if the user already uses other Xfinity products – such as internet or TV service – and the phone service can be included in a bundled package, saving you money.
