For the kamailio 3.0.x release, the (s) modules were not included in the binary distribution (the modules.lst did not include modules_s_all). I see that for upcoming kamailio 3.1.x release, while building the modules list by using 'make FLAVOUR=kamailio cfg' the modules_s_all is present in the modules.lst. Is this done on purpose? Do we want to ship the (s) modules with kamailio? Regards, Ovidiu Sas
