I had time to test it with the computer of my parents via SSH.

Whatever I try from there it works. From both sides I can connect and get 
So how shall I say, I think I have a problem only with the ekiga callback 
I spent so many thoughts about it. I think the problem started, when I tried 
to ask for a callback with only theora codec enabled. Your server does not 
support it and delivered no video. Then I enabled the H261 codec again and 
Video never worked again.

I don't believe it is your server. My potential reason is my Fritzbox. Maybe 
there is a mechanism that should protect me or so... I have asked them. I they 
answer something interesting, I will come back.

Thank you Damien for your continued support. I learned so much about SIP and 
how the video travels in its packages over the net :-)
