Hi Bogdan,
So OpenSIPS module is not derivative.

I have found this page : http://people.gnome.org/~markmc/openssl-and-the-gpl.html
and at the end : "all the copyright holders for the affected code agree"
and

Hi Binan,

Just to clarify on the "module" thing - an OpenSIPS module is a
      shared library that is dynamically loaded by OpenSIPS core at
      runtime. So, there is no linking between core and modules, but
      they share and use code.

Secondly, the non-GPL lib will link only to an OpenSIPS module,
      without being linked or used at all by the core part.

Maybe this will help a bit .

                  needs to be stated by the copyright holders of this
                  new opensips module (that will link to the lib) or by
                  all copyright holders from core + module ? This is the
                  tricky part :)
