Hello Daniel,

I think that debugger module was released with Kamailio version 3.1.0. wasn't it? 
As I'm running Kamailio 3.0.0, I have set up debug=9. 

Here you have my config file, the raw capture of the call and the lines in kamailio log file. 

I see some messages regarding cpl-c module, and I was experiencing some problems with it too. I tested without cpl-c module and I get the same trace but no messages in log file.


Thanks in advance.

Regards.

Luis.
