1und1 Provider registration failes

[Ripkens]

Hello,

i have setup 3 VoIP numbers from 1und1 using the 1und1 provider template which i found in the wiki.

All trunks show "Not Registered"

Additionally i found this in the Logs:

23:39:13.265 [CM305004]: Failed to find a transport to host 192.168.178.201

23:39:12.671 [CM305004]: Failed to find a transport to host 212.227.15.231

The first line comes from my 3CX client and is also wrong, but the softphone works
The second line is about the provider sip.1und1.de

How do i fix those transport problems?

regards
Marcus
