Olle , Thank you very much for your reply! I am not the root user on the unix system. but I want to customize the log file for the function: xlog. Now, I don't know where to see the content what xlog writes. It can help me to debug the script of kamailio.cfg i edited. what i do is collect the CDRs by dialog and acc modules. Any suggestion will be appreciated. Thanks a lot ! ------------------ albert.gu ------------------ Original ------------------ From: "Olle E.

The configuration file is propably in the /etc directory. Try running "man syslog.conf" for more information about that file. /O _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
