[SR-Users] SEMS license with kamailio and rtpengine

[Alex Balashov]

Yes, I was trying to keep it simple, but perhaps, as you say, at the cost of some accuracy. :-)

Most laypeople’s understanding of what it means to sell software, in my experience, is to distribute it in binary form without offering the source, even upon request. This is what I meant to say was forbidden.

Nobody else than the buyer has the rights to request the source code.

>> Then you should not have any problem using SEMS as an input into commercial services. :-) As a general rule, open-source licensing is not concerned with _how_ you can use the software, only how you distribute it and/or any modifications you make to it. Think, for example, about something like Linux, which you are likely also using. You are free to use Linux to make money.

I would take the time to research it, get familiar with its basic premises, and, of course, consult a lawyer if you have any truly esoteric questions.
