Hello Wei,

I am not a lawyer, and for a definite answer to your particular case I'd 
suggest you consult one.

You are correct, Kamailio is licensed mainly under GPL2 or later. The core is 
licensed under the BSD license.

About your question: 

Kamailio interprets the routing script during run-time. This does not enforce 
a certain license on this particular Kamailio configuration script. You as an 
author can choose a license that you prefer.

You will find a more extensive explanation in the GPL FAQ, first paragraph:

https://www.gnu.org/licenses/gpl-faq.html#IfInterpreterIsGPL

If you e.g. sell a Kamailio script to a customer, the customer can of course 
access the script and look to it. It is available on the server in the end. 
But this does not alter your right to choose a license.

Best regards,

Henning
