Hi All, I am configured kamailio to handle reg info event subscriptions, My server is running if i configure the following parameter. #kamailio local ip is 192.168.20.20 *modparam("pua_reginfo", "server_address", "sip:reginfo@192.168.20.20 &lt;sip%3Areginfo(a)192.168.20.20&gt;&quot;)* If i am not configured the above server address, i am getting bad configuration Oct 18 11:31:36 arm /usr/sbin/kamailio[2787]: INFO: auth [auth_mod.c:333]: mod_init(): auth: qop set, but nonce-count (nc_enabled) support disabled Oct 18 11:31:36 arm /usr/sbin/kamailio[2787]: INFO: permissions [parse_config.c:251]: parse_config_file(): file not found: /etc/kamailio/permissions.allow Oct 18 11:31:36 arm /usr/sbin/kamailio[2787]: INFO: permissions [permissions.c:607]: mod_init(): default allow file (/etc/kamailio/permissions.al... rule set Oct 18 11:31:36 arm /usr/sbin/kamailio[2787]: INFO: permissions [parse_config.c:251]: parse_config_file(): file not found: /etc/kamailio/permissions.deny Oct 18 11:31:36 arm /usr/sbin/kamailio[2787]: INFO: permissions [permissions.c:616]: mod_init(): default deny file (/etc/kamailio/permissions.den... rule set *Oct 18 11:31:36 arm /usr/sbin/kamailio[2787]: ERROR: pua_reginfo [pua_reginfo.c:105]: mod_init(): server_address parameter not set* *Oct 18 11:31:36 arm /usr/sbin/kamailio[2787]: ERROR: <core> [sr_module.c:944]: init_mod(): Error while initializing module pua_reginfo (/usr/lib/...ginfo.so)* Oct 18 11:31:36 arm /usr/sbin/kamailio[2787]: INFO: <core> [sctp_core.c:53]: sctp_core_destroy(): SCTP API not initialized Oct 18 11:31:36 arm kamailio[2771]: already running ... failed!

I want to know what is the significance of this parameter and find no where this value is used. Thanks in advance. Regards, Raman
