Why would you think $20/year would provide any kind of quality, reliability, or integrity?
Before I upgraded to FIOS from RoadRunner, getting 50% more bandwith and 100% less problems all for about 45% less money, I canceled the phone portion of my account.
I recommend you shop around for a VoIP (voice over IP) phone provider that has the features- and price you want.
Some top rated providers, some of which I have personally tested include:
TWC is offering the same phone "feature" set as available from the Bells in the late 1970s. That's yet another way they gouge you.
If you are a little adventurous research the feasibility of setting up an asterisk server in your home to save serious cash on your phone costs. A user friendlier option is PBX in a flash; "orgasmatron" is a popular ready-to-go package. Once you swallow the cost of a server, as little as $300, you can get flat rate incoming calls for as little as $3 per month (or pay by minute rates similar to outgoing) and outgoing calls billed as little as $0.0105/min. You will make NO sacrafice in quality when correctly configured unlike some of the other choices in the market.
