I just install gizmoproject on my n800 and I have to say it works better than skype. I called a few people using skype and all complaint about how choppy my voice is when on skype. Now I did the same thing from gizmoproject no complaints at all and some thought i was on a landline :P . I have all the ports skype needs to be open for good call quality and still sounds bad and i havent set not even one of the ports gizmoproject needs and sounds excellent Would love to hear other users experiences with both apps later!
