Because your client puts private IP addresses in packets. When doing so, if you contact another Ekiga.net user, there will be no audio / video.
The only solution to that problem would be that we relay the audio and video streams through Ekiga.net. That's something sipphone.com can do for paid calls (from/to PSTN).
