Skype vs GizmoProject (continued....)

A friend of mine pointed out that a couple of Gizmo users disagreed with my assessment of Gizmo's voice quality -- check out http://forum.gizmoproject.com/viewtopic.php?t=8310 . Two questions were raised about my process of assessment...

1. Was Skype running when I tried the Gizmo?: Yes, Skype was running when I initially tried the Gizmo. After reading the comments on the forum, I have tested the Gizmo without Skype running. Even without Skype running on my PC, Gizmo's voice quality tunred out to be inferior than Skype.
2. Length of my testing: I have to admit that I've probably recieved less than 10 calls so far on the Gizmo; all my calls were forwarded by GrandCentral (not sure if that makes difference in the quality).

After reading through some of the posts on the Gizmo forum -- I've decided to not give up on the Gizmo. In fact, just ordered a couple of GrandStream ATAs so that I experience the voice-quality with Gizmo on . I already have the Philips cordless Skype phone and will post a comparison in a couple of days.
