Nintendo DS hack for SIP VoIP service via WiFi

This January, I began a list of VoIP services for the Nintendo DS, which we know contains a WiFi connection and a microphone headset.

At that time, none of the solutions included support for the popular open SIP protocol. Now, a French developer has released an early version of SvSIP, which lets you make phone calls using your homebrew-enabled DS and a SIP provider. He seems to be actively updating it, and we should see some new versions available soon on his website.

To complete the list, another French developer has been working on DSiP, a rival alpha VoIP client for the DS. The author seems to no longer have time to work on it, but promises to release a working version.
