Saving bucks using internet phone

Some people drop their landline phone and use a cell phone only. From home, the quality of my cell phone is not very good. I still want a landline phone so I don't have to question if my caller can understand me. But there's another option... Two months ago we ditched our landline (and the monthly payments of $38) and bought an internet phone device. Our one-time hardware investment of approximately $220 will be paid off after about 8 months. I would say the service is free except we have to pay a few dollars each month for communications tax.

The voice quality is good, far superior to my cell phone. The vendor we use is OOMA.
