I'm not a SIP-protocol expert. Can you explain me how you see
this for the above message? Is it because of the asterisk in the
Contact header? I have searched, but couldn't find the meaning
of the * in the Contact header.

with tcpdump and wireshark for my SIP-protocol debugging...

OK. And for as far as I understand it from
ekiga.net should not sent this 606 error, right?
So the conclusion is that the problem is actually on the
ekiga.net server side and I have to hope that it gets fixed?
