I travelled in Asia and needed to call back to Canada quite a few times. Compared my skype experience, I think this one is 20% better in terms of the voice quality and clarity. But room for improvement is still big. The best thing I like about this app is the flexibility in making LD call with the confident that the other end of the line is able to hear my whole conversation. Unlike skype whereby we can keep talking and not knowing the other end is disconnected or couldnt hear a word from us. Its a lost feeling or quite embarrassing experience.
