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 .
