What am I trying to do:

What am i doing wrong?

As quoted above:
Asterisk 12.0.0 built by root @ asterisk1 on a x86_64 running Linux on 2014-01-14 15:37:23 UTC

Regarding the results of the commandline execution, nothing unexpected, the output was already verified on TCP level.

Can you help me any further than this?

Nicolás, I understand your situation. We really appreciate the help and we are trying to be as verbose as we can on this.

We're building a test setup to implement in our callcenter/support setup.

If this issue is indeed the one you suggest, this problem will persist in all future versions of Asterisk and it is worth looking into. Could you post your findings and a possible fix?

This seems to be succesful.

When running as server daemon I get prompted the Login details now. It seems that the problem is solved!
Just out of curiousity, was the problem the response header?

Thank you for this, we can now proceed with implementation tests :D
