I think Opensips modules are considered derivative to the core ( OpenSIPS module needs "help"
from the core. It is not stand alone ).
Special exception clauses can only be applied to an original work and never a
derivative. If the core is linked to the lib then all the copyright
holders of the core states the exception.
You can go around this by considering this module as part of original work not derivative. In this case we backed to above (All must state the exception).
This must be confirmed by IP lawyer.

And this exception clause (btw, found something similar here
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 :)
Thanks and regards,
