[SR-Users] SEMS license with kamailio and rtpengine

[Daniel-Constantin Mierla]

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
