ooma good
 

My ooma is about three years old. I bought it when it was the only service that would without a PC running. It has been he best service I have ever had. When I am away I get an e-mail on my lap top that I have a Voice Mail. Then I can go to my.ooma.com and listen to the v-mail.
Never more than $5.00/mo.
Very reliable.

I believe that is the correct term. AT&T, Uniden, Motorola, and a few others make them. They come with a base station and handset, and usually 3 or 4 other handsets that sit in a charger. The base station needs to be pluged into the Ooma box and the other handsets someplace else in the house. With this set up, traditional through the wall phone jacks are not used.
