Someone will probably correct me, but it looks like you are trying to 
use the g729 codec for your calls (or coco-connect.de is forcing you to 
use g729), but this requires a license from Digium and is not installed 
on your machine.

Try using a different codec if possible or, if you do have a g729 
license try re-installing the codec and re-activating it.

I think this may solve the problem. But as I say, someone may correct me 
- I may be completely wrong about this.
