[Asterisk-Dev] GPL Licensing Question

[Michael Giagnocavo]

I understand that Asterisk is GPL'd, but Digium retains copyright, and thus
can grant exceptions. So a company would need this if they modified the
Asterisk code and wanted to sell it as a proprietary, closed-source
solution. On the other end, anything just using Asterisk formats or
protocols (say IAX, dropping a .call file in the outgoing spool, or editing
.conf) wouldn't need any licensing.

How exactly does this work in regards to modules? As I understand, code that
links to GPL code needs to be GPL also. Does this mean I can't write a
module that links to Mono (which is LGPL and MIT X11 licensed) even if my
module code is GPL? 

 

Thanks,

Michael Giagnocavo
