Is it worthwhile to consider building a low cost PC as a land line replacement? Right now I pay $40 per month through my cable provider. This PC would be always on, so low power consumption and longevity is important. I would like to keep my existing phone number so is that a limiting factor?
I was looking at Skype, Net Talk, Yahoo Phone Out, etc. A couple of these services purport to offer number portability as a future service. I believe I can use ParkMyPhone.com to retain my number until then. If the cost of the PC hardware is low enough, it might be worth it as the calling is very low cost with these services. If I could get payback within one year, that would be ideal. It just looks like it is hard to beat Ooma's $200 cost.
