Voipstunt offers free international calls using their free software. There are a lot of these Voipstunt like services so what is the difference? Well with all of them they will let you make free international calls of up to 5 minutes. By free international calls I mean to an extent. You can’t call every international call you want, only a select few.

Voipstunt… Should I buy credit?
I bought credit with a similar service. I used JustVoip.com because of their 9 euro cent a minute calls to German cell phones. By buying credit I can call a whole load of international numbers with a one hour time limit. If you don’t buy credit you can still make free calls up to 5 minutes long. Eventually your credit will run out and your account will no longer function. The solution? Make a new account…
