I have been using Skype for a while and wanting to find an open source
Skype uses encryption which most of the open source counterparts lack.
Also, with skype it's not a direct connection between the two PCs, I think
they use nodes/super nodes or something similar in the middle.
I know Ekiga can be used to call directly with h323 protocol but it lacks
native encryption, to make it secure I will have to either use ZRTP or have
VPN set up.
Is there a simpler alternative that allows for direct IP to IP voice
communication and is secure?
