Hi Benny! I think it would be useful to add to the documentation void(* pjsua_logging_config::cb)(int level, const char *data, pj_size_t len) http://www.pjsip.org/pjsip/docs/html/structpjsua__logging__config.htm#6e5842ac5598a2d953184d9b8bf86628 that the "len" parameter is not used and data is a null terminated string. regards klaus
