Looking into VOIPBuster vs Skype for cheap VOIP calls expecially when I goto Uganda (more about that in a later post) I find that:
If you buy VOIPBuster credit you get 120 days free period where you can make free calls to countries unfortunatly for us Uganda or South Africa isn't :-( So nothing is going to be free.
Comparing the prices:
0.060 EUR = R0.797024 (Landline)
0.170 EUR = R2.25728 (Mobile)
So VOIPBuster is cheaper for landline but Skype is cheaper for mobile.
