I downloaded SipDroid from Android Market. In SipDroid I set my username (i tried both the Gizmo phone number i got and my userid), password using my Gizmo5 info. I then put for the server: proxy01.sipphone.com. The dot in the top right corner of the phone is yellow, and then goes to red. I am unable to get a green light on it. Any idea what is it? I need an advice on this. Thank you in advance.
