Anybody tried the GTalk2VoIP voice gateway on the 2006 software edition? http://www.gtalk2voip.com/ Freeswitch is another interesting project. http://www.freeswitch.org/ I haven't upgraded my N770 yet. But I would the moment I'm sure I can use my VoipDiscount account (SIP) on it, with free calls to fixed lines in 50 countries, and my own VoIP-in number.
