[OpenSIPS-Users] [OpenSIPS-Devel] [HELP] Advising on GPL license issue

Tue Dec 4 11:21:00 CET 2012

Hi Binan,

I found that page in the very beginning of my search and, indeed, it 
provides really useful information on this case.

About the statement, I understand that "affected code" is the code that 
uses (directly or indirectly), compiles or links against the library - 
which will be the opensips module. Correct ?

Regards,
