[Blink] Config problems with 1&1 SIP provider

["Robert M. Münch"]

Hi, I have a problem in that I can make calls out with OSX/Blink, but can't receive calls. Blink is not reacting in any way.

I get this in the log for activity:

2011-02-25 12:45:31   Error: The account 49...... at sip.1und1.de failed to register(No more routes to try)
2011-02-25 12:47:56   Account('4972162597734 at sip.1und1.de') failed to register: No more routes to try (retrying in 41.05 seconds)

Any idea, how to configure for 1&1? I use Telephone VOIP client on OSX and there it works. It has a DNS SRV or so check mark that needs to be set.
