Although Comcast isn’t the best VoIP provider on the market, the cable giant provides a respectable VoIP solution through its XFINITY brand. The service provides most of the plan options and calling features we looked for in VoIP services, but it’s short on additional phone services. Therefore, Comcast VoIP is best suited for residences rather than small businesses looking for a full-featured VoIP system.

Comcast offers just two VoIP plans: an unlimited plan and a local calling plan. The local plan is quite restricted and, as its name denotes, is limited to local calls only. The VoIP provider charges by the minute for any long-distance calls. The service’s unlimited plan is definitely a better value, with unlimited local and long-distance calling for just a few more dollars per month. The unlimited plan also includes calls to Canada and Puerto Rico and voicemail (you’ll have to pay an extra monthly fee for voicemail on the limited plan). Both plans, however, offer 12 common calling features, including call waiting, caller ID and three-way calling.

A few other notable things about Comcast is you can keep your current phone number and you can use the service month-to-month without a contract obligation. The monthly fees are higher than many of the other VoIP services we reviewed, but Comcast is ideal if you don’t to want to be roped into a contract with your phone service.

Comcast’s basic calling is excellent, but the service’s additional phone services are limited compared to the other VoIP providers in our lineup. While you can add additional lines, Comcast doesn’t provide a softphone, toll-free numbers, virtual phone numbers or fax support on its VoIP lines. Comcast does offer separate VoIP services designed for small to medium-sized business that need multiple extensions.

With Comcast’s solid reputation comes excellent help and support options that surpass most competitors. You can fully manage your VoIP system through the Comcast website, whether you want to view your latest bill or upgrade your service. This VoIP service provides a knowledgebase and FAQs that you can browse if you run into issues, or you can contact the company directly via telephone, email or, the most convenient option, live chat on the Comcast website.
