GNU, GPL, Open Source The GNU Project has announced a new project called GNU Free Call, an open source Skype alternative that will offer anonymous VoIP and will use the GNU SIP Witch server as the back end. GNU SIP Witch requires a minimum of system resources so it can be used on cell phones too so it seems the goal is to provide a cross-platform application, the immediate target most probably being Android.

The problem is not SIP, it's IPv4. IPv4 is obsolete since more than 20 years now. We just can't seem to get rid of it. We will have to deal with NAT and hacks around NAT until the end of time or until the Internet implodes.
