Chris at GRYNX.com has a great DIY post on free VoIP(Voice over Internet Protocol) calling. Chris says...
I’ve been a regular user of Skype for about a year now and have been
using my own solutions to try to make this as user friendly as
possible. But it was never perfect and I’ve always been the only one in
my house using it as it hasn’t been user friendly.
Then I heard about the Sipura and started looking around on how to use it, and then I heard about VoIPBuster which provided free VoIP calls to land lines all over the world.
But - there’s always a but - it wasn’t as easy as I wanted it to be to get everything up running. I eventually figured out how to actually get a user friendly, transparent, phone solution up running and now anyone in my house can pick up any phone and the Sipura takes care of routing the call the cheapest way.
In this how-to I will explain why I made the choices I made and show
you how easy it can be to have this up running in your own house.
Calling nationally and internationally for free to regular telephones.
