Phone calls are not really free as such yet. For your regular use, a paid subscription is normally required, but there are people whose communication needs are not that bulky and for whom therefore free services work just fine. Now, one way of calling unlimitedly anywhere for free is to use software-based servicesover the Internet and make sure that the callee is using the same service as the caller, a condition which is most of the time inconvenient and sometimes unrealizable. Here are some ways in which you can make calls locally and internationally to any phone, fixed or mobile, worldwide for free.
1. VoxOx
VoxOx aims at unifying all communication channels for users. One main feature is very cheap calling worldwide through their softphone. Upon signing up, you get 2 hours free talking time to any destination in the world. Now this is a lot. If you want to get more talking time, have your friends sign up under your reference, and for each friend, you get another two hours.2. Tuitalk
Tuitalk allows you to make free calls everyday without ever claiming a dime. Where is the catch? The calls are sponsored by advertising. Before making a call, which basically lasts no more than 10 minutes, you have to watch a 30-second advertising video that loads in the application's softphone itself. And then, you can call people in only 35 countries so far.
