Okay - let me put that straight:
I can use ekiga with the WAN IP of my router as registrar (since it 
works obviously perfectly) but I can't use the dyndns which should be 
(per definition) nothing else but a mapping between hostname an ip. It 
sounds a bit weird to me.
Also I don't use the voip provider directly (which I wanted to make 
clear by saying: the registrar is my router).
It is connected to the isp (which in my case is the voip provider) and 
forwards calls to it's clients - e.g. ekiga (or the "normal" telephone). 
And since it shall forward the calls not only in LAN but over WAN, I 
need to tell ekiga the WAN ip of my router - and here I want to use 
dyndns.....

So you see: in this loop there is dyndns which doesn't work :(
