Re: [SR-Users] SEMS license with kamailio and rtpengine

Hello, regarding selling copies and the source code fee, the quite extensive GPLv2 FAQ covers it extensively: https://www.gnu.org/licenses/old-licenses/gpl-2.0-faq.html#DoesTheGPLAllowD… Nobody than the buyer could request the source code, but each buyer can of course distribute the source code freely: https://www.gnu.org/licenses/old-licenses/gpl-2.0-faq.html#DoesTheGPLRequir… Cheers, Henning -- Henning Westerholt – https://skalatan.de/blog/ Kamailio services – https://gilawa.com<https://gilawa.com/> From: sr-users &lt;sr-users-bounces(a)lists.kamailio.org&gt; On Behalf Of Daniel-Constantin Mierla Sent: Wednesday, February 9, 2022 8:09 AM To: Kamailio (SER) - Users Mailing List &lt;sr-users(a)lists.kamailio.org&gt;rg>; Patrick Karton &lt;patrickarton(a)hotmail.com&gt; Subject: Re: [SR-Users] SEMS license with kamailio and rtpengine GPL software can be sold without problems, there is no restriction on selling it, but the buyer can request the source code and it has to be provided (afaik, source code delivery could also have a price, but not exceeding the value of the binary form -- this remark must be validated with a lawyer). Nobody else than the buyer has the rights to request the source code. Cheers, Daniel On 08.02.22 21:36, Patrick Karton wrote: Thanks again Alex :). I will make further read about FOSS licensing. Using open source at large scale is relatively new for us. We have Law department so WE will discuss in more details about it. Thanks again.

Think, for example, about something like Linux, which you are likely also using. You are free to use Linux to make money. However, it is surprising that you are not familiar with the GPL (GNU General Public Licence), since it is all but ubiquitous and probably the most popular open-source licence out there. 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. — Alex -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ __________________________________________________________ Kamailio - Users Mailing List - Non Commercial Discussions * sr-users@lists.kamailio.org<mailto:sr-users@lists.kamailio.org> Important: keep the mailing list in the recipients, do not reply only to the sender!
