Hi Adrian, thanks for the elaborated explanation. I know some big guys at 1&1 and will see if I can use my channels. Even this won't necessary result in a fast fix. But if we don't try, we will never know. We will see.

I'm sure you know the "Telephone" VOIP client for OSX. This one works for me, from different setups. Even if it's pure luck, than I'm a pretty lucky guy because I never had a problem with it. Beside crashes of the progam, which might be caused by exactly what you described. But restarting helps and than it works...

How about letting me choose to use the undeterministic approach and taking the result AS-IS? That would be OK for me. If I'm as lucky as when using "Telephone" than my problem is solved.

How about both ways? Robert
