Hello, lines starting with # (or what is after # in a line) are comments, excepting the #! preprocessor directives. So the loadmodule for counters is a comment. See more at: https://www.kamailio.org/wiki/cookbooks/5.2.x/core#comments https://www.kamailio.org/wiki/cookbooks/5.2.x/core#config_pre-processor_dir… Also to have in mind for the future, sr-dev mailing list is intended for development discussions. Question related to configuration file and use of kamailio have to be posted to sr-users mailing list.
