I used to have a free softphone (I don’t want to name it) with poor voice quality and I got totally fed up with it so I decided to change it for a better one. I tested then I purchased Ozeki VoIP SIP SDK and the video and voice quality seems to be all right: Addressing video quality sample program was a great help for me. It supports many codecs and is compatible with lots of open source pbxes like Asterisk. Have you got similar experiences ? Any bad points?
