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?

Thanks & Regards,
Yan
