Hello, I am still trying to install a presence server and a RLS. What I understood is that I have to install the xcap module on Kamailio and a Xcap server. I began with the pua and xcap_client module. When installing xcap_client I have the following errors: xcap_client.c:162: attention : implicit declaration of function «curl_global_cleanup" make[1]: *** [xcap_client.o] Erreur 1 make[1]: quittant le répertoire « /opt/kamailio-1.5.0-tls/modules/xcap_client » make: *** [modules] Erreur 2 And when I am restarting kamailio server (I've added "loadmodule pua.so) I also have an error (I am in the debug mode) Mar 25 10:12:48 [11907] ERROR:core:db_check_table_version: invalid version 5 for table pua found, expected 6 (check table structure and table "version") Mar 25 10:12:48 [11907] ERROR:pua:mod_init: error during table version check. Mar 25 10:12:48 [11907] ERROR:core:init_mod: failed to initialize module pua Mar 25 10:12:48 [11907] ERROR:core:main: error while initializing modules I have kailio 1.5. Thanks for your help, Loredana
