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#DoesTheGPLAllowDownloadFee
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#DoesTheGPLRequireAvailabilityToPublic Cheers, Henning -- Henning Westerholt – https://skalatan.de/blog/ Kamailio services – https://gilawa.com<https://gilawa.com/> From: sr-users <[email protected]> On Behalf Of Daniel-Constantin Mierla Sent: Wednesday, February 9, 2022 8:09 AM To: Kamailio (SER) - Users Mailing List <[email protected]>; Patrick Karton <[email protected]> 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 > On Feb 8, 2022, at 2:50 PM, Patrick Karton > <[email protected]><mailto:[email protected]> wrote: > > Thanks for explanation Alex. > > Im a service provider. > > Le 8 févr. 2022 20:14, Alex Balashov > <[email protected]><mailto:[email protected]> a écrit : > You can Google the meaning of “per se” for a richer explanation, but it means > “as such” or “the thing itself”. :-) > > “Per se” in this context means that you cannot sell SEMS as a _software_ > product, because it is free software. > > Are you a service provider, or are you in the business of selling software > for service providers? > > > On Feb 8, 2022, at 12:37 PM, Patrick Karton > > <[email protected]><mailto:[email protected]> wrote: > > > > Hi Alex, > > > > Thank you very much for the response. > > > > i did not understand your last phrase "You may not, however, sell SEMS per > > se". what is per se ? > > > > as i said i only want to use the sems sbc module and eventually annoucement > > and ivr module. but thats all the functionnality i want from sems. > > > > -- > 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 > * [email protected]<mailto:[email protected]> > Important: keep the mailing list in the recipients, do not reply only to the > sender! > Edit mailing list options or unsubscribe: > * https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users > > > __________________________________________________________ > Kamailio - Users Mailing List - Non Commercial Discussions > * [email protected]<mailto:[email protected]> > Important: keep the mailing list in the recipients, do not reply only to the > sender! > Edit mailing list options or unsubscribe: > * https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users -- 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 * [email protected]<mailto:[email protected]> Important: keep the mailing list in the recipients, do not reply only to the sender!
