OOMA

We have had an ooma phone system for over a year now and are satisfied with the performance. Ooma works by selling an internet ready box into which you plug your phone system or it can adapt to energize your home phone wiring.You get phone service  for no fee at all, or you can get 2 lines for 9.99 monthly. Overall, it is cheaper than Verizon and more reliable. You need cable internet, and Oooma is basically as reliable as your cable and electricity allow it to be. Ooma itself has only been out of service a few hours on 2 days in a year.
We got our Ooma from Best Buy for around $200, but we eliminated a $56 monthly bill.We now have reliable service, we did not have reliability with Verizon. Any phone will work with Ooma, and it does everything but cook and clean, I don't use any of the extras but the second line, and the second line feature is the only one that costs anything monthly. Long distance in the U.S. is nearly unlimited, there is some charge for international calls.Check it out. My system is often available for $165 on the web and sometimes at Best Buy.
