If you using gizmo5, when phone rings, it created a new gizmo page. So you have to go back to the 1st page (the home page when you log in) and looked under the task bar, there is a phone icon. Hit that phone icon you will get a dial pad and press 1 will answer the phone. I know, i know, it is not perfect, but hey, it is fun, right?

The other question has something to do with your configuration on the grandcentral, play with it, then you will not calling yourself

I am glad you like it. Correct, this is NOT a replacement for your cell, but it is a hack that I think is pretty fun and also useful at time you need to call somebody and has only wifi and tablet... you got the picture.

Edit: Oh, if you are using DialCentral, it called back you hang up and answer, that is the way it is.
