Hi everyone was just adding a money saving tip in the Lets try to name 1000 money saving hints!!! thread and realised I hadn't kept up with free call software after I found skype, I'd used many different pieces of software that came with webcams and even Microsoft Messenger for many years, think from about 1999 or 2000, until it was rolled into skype. Now I was curious to know what people recommend?

These are the two main ones I know of:
Skype - Free internet calls and online cheap calls to phones and mobiles

Viber works on Desktop computers, iOS, Android, Windows Phone, Blackberry, Bada, Nokia and it's free for the basic packages:
Viber - Free calls, Free text messages, photo and location sharing

Any others worth having a look at?
