Okay I finally got on to it, it has a clunky IE based interface and It does not support confrence calls. I have not tested the sound quality much but it seems fine. The one and only thing this has over Skype is free incoming calls with voicemail, which works with some local access numbers and the person who is trying to reach you enters your pin. Overall Skype has a way better service, but if you're looking for free incoming calls or maybe just a free voicemail then go for it.
