I'm new to this whole VoIP thing. I looked into it some months ago but hadn't taken any action yet. My situation is this: I don't talk a lot on the phone. Currently, the cheapest plan I found was BroadVoice in state calling which is $9.95 a month.
My question is: Is there a plan which you pay as you go along on a minute basis? I've found the website LiveVoIP which seems pretty cheap (you must of course by initialliy lots of minutes - but still cheap). There are some terms out there I don't quite understand: Asterisk, Sipura. Can please somebody explain to me exactly what these things are and are they complicated/complex to install?
Ideally (and it probably doesn't exist), I would like to have a phone which I can use to call other people and other people can call me which uses VoIP technology. In order to minimize costs, I want to pay as I go by the minutes.
Any insights will be most helpful.
