I've recently downloaded this computer phone-app and it is highly recommended. It is not a video chat program. It is only for calls to landlines and cellphones. It is completely free. The only thing is that it plays ads/videos. But they can be paused, or muted. Also, you have to submit your email to make it work. They do not send you spam (as far as I can tell so far) They do not collect your personal videos, conversations, and pictures the way Skype does.
