I started using Voip last weeks but don't know yet which one to use!I used Voipdiscount,Skype,Jajah and eVoice.The last one is available only in Greece.All of them want money!And they have alomst the same rates!And don't believe that "Free Calls Everywhere" they have on their websites.Skype needs too much RAM,so I will not use it again.Jajah is nice and has good quality.Voipdiscount says that you can make free calls to many countries but after I made 3 calls it said that now I have to pay 10$ in order to get more free calls.How will they be free calls if I pay?Anyway,I think I'm going to stick with eVoice because at least they have support.
