Yes I am sure. Today I let it run for good 5 minutes... The same result. Do 
you aggree, that the reason must be that the video packages do not reach me?

I have not understood completely the mechanisms around SIP. Which component 
(me or the server) is doing the connect action? 

My computer is not restricted in accessing the internet (in to out). From 
outside I have forwarded the ports in question and allowed the internet to 
connect to those ports.
What is the difference between the echo and the callback request in matter of 
the return video transmission?
What is happening behind the curtain?

Thanks for your time and patience!
