kurun: Yes, thanks for testing that. I was about to report the same success as well!
DracoFelis: Gizmo5/SipPhone seems to keep some of their advanced options in the desktop client. e.g. Changing/recording voicemail message and SMS voicemail alerts (although the former you can do on your phone and the latter option hasn't worked for me).
Now that it is forwarded...most of the settings don't matter anyway.
