there is some erroneous information that Kamailio core uses another, more

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

That’s wrong. You may sell GPL-licensed software. But if you changed the code,

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).
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.Le 8 févr. 2022 20:57, Alex Balashov a écrit :Then you should not have any problem using SEM
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 Li

You can Google the meaning of “per se” for a richer explanation, but it means

“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 so
from sems.

You do not need to purchase a licence to incorporate SEMS into a service
platform to sell telephony to customers. You may not, however, sell SEMS per se.
That’s the very, very simple version.
