EnGadget recently had an article on getting power from your POTS line. While this is real cool I have the same question as EnGadget, Who is still using POTS ? In my home I have a SNOM 360 and SPA-841 for my calls. I can make a total of 14 concurrent calls. I think the only need for a POTS line is to have DSL come in for your home as well as emergency power when the power lines go out. Click here to see the article on EnGadget.
