Hello, 
I have a question about the license of Kamailio. 

It is said to be GPL in https://www.kamailio.org/w/:
"Kamailio® (successor of former OpenSER and SER) is an Open Source SIP Server released under GPL, able to handle thousands of call setups per second...."

But GPLv2 in https://www.kamailio.org/w/info/ :
"Kamailio  is released under GNU Public License v2 (GPLv2). Beginning with 3.0.0, the application includes parts of code under BSD license that can be used such as individual components."

Which one is the correct description?

actually it is GPLv2 or later, as the header of main.c file lists:

  * https://github.com/kamailio/kamailio/blob/master/src/main.c

All (almost) source code files have the header with their license, several files/modules have also BSD license, if you want to use (extract) them individually. But over all, it is GPLv2+. Somehow GPL as a term got associated mainly with GPLv2 over the time.

I updated the the web pages.

Cheers,
Daniel
