I would also like support TLS 1.2 and TLS 1.3, but remove support for 1.0 and 1.1 Thanks, Arik Halperin _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org <mailto:sr-users@lists.kamailio.org> https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users <https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users> _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users

In this case you have to specify there the parameters like ciphers, because the module's ones will be ignored: http://www.kamailio.org/docs/modules/5.3.x/modules/tls.html#tls.p.config <http://www.kamailio.org/docs/modules/5.3.x/modules/tls.html#tls.p.config>.
