Firefox hello
Firefox Hello lets you make free video and voice calls directly from the
browser. All you need are a microphone, a webcam (optional), and the latest
version of Firefox to call friends who are on WebRTC-supported browsers like
Firefox, Chrome, or Opera.
Jitsi Voice Call
Jitsi lets you communicate with friends and contacts across the Internet.
Jitsi prevents eavesdropping by automatically encrypting your conversation
for the full duration of its trip across the Internet (“end-to-end
encryption”). This means that even your voice calling service (Google,
Facebook, Jit.si, etc.) cannot listen to the contents of your call. For full
details see “Limits of end-to-end encryption” below.
They are great, but when you need to get out of your internet network to dial
a landlines or cellphone it does not support it. Either you end up paying for
it or no grease talk at all. That what separates the BIG BOYS from Skype FROM
THE REST,,,
