Remko,

What IP's do you get returned for sip.voipbuster.com?
Do you use UU-net's DNS servers? If so, you might try using different
servers, as I have had some weird experiences with their DNS servers in
the past.

Have you tried trace-routing to the server to see where it breaks?

I am using voipbuster as well, and am usually able to connect just fine...

Good luck!
