The Ooma VoIP system is our recommended VoIP provider. It's relatively inexpensive, with the taxes and fees calculated based on your zip code, and you can check that out here. In the Boston area the taxes and fees usually total up to $5.09/month, but please check your specific costs on the site.
We also provide the hardware for Ooma for free to our Starry Internet customers! If you'd like we can schedule a time for one of our techs to come over to install the hardware for you and get it set up.
