I have found (actually, I simply "bumped upon") some links to A SUBSTITUTE to an AT&T- (wired) home telephone setup.

What sort of setup is a V.O.I.P. (Voice-Over Internet Protocol) system? If I do use this system instead of my wired telephone setup, what hardware will I have to use?
%Will I need to leave my P.C. powered up and running all day and night long to continue an access to this system? Am I correct to assume if I turn off my P.C, I will not be able to make or receive calls?
Thanks for feedback.

Very curious if I can get digital phone through a satellite internet provider. Hmm.

Will be making the switch soon, and thought I'd ask to see if others have had either good or bad experiences w/it..

I would like to hire someone to create a VOIP software customized to my own specification. Since I do not know much about this, I would like to know how much it would cost to hire a proffessional to do the job for me.

If I could be reffered to a professional, I will be grateful
