Hi, Downloaded Kamailio-4.2.1.tar.gz file from Kamailio.org site and compiled it on RHEL 6.2 server. Configured as per setup instruction given in attached document. While start pcscf, getting the following errors: Jan 20 01:25:17 localhost pcscf: INFO: <core> [ppcfg.c:80]: pp_subst_add(): ### added subst expression: /PORT/4060/ Jan 20 01:25:17 localhost pcscf: INFO: <core> [ppcfg.c:80]: pp_subst_add(): ### added subst expression: /NETWORKNAME/open-ims.test/ Jan 20 01:25:17 localhost pcscf: INFO: <core> [ppcfg.c:80]: pp_subst_add(): ### added subst expression: /HOSTNAME/pcscf.open-ims.test/ Jan 20 01:25:17 localhost ./pcscf[4201]: INFO: rr [../outbound/api.h:54]: ob_load_api(): Failed to import bind_ob Jan 20 01:25:17 localhost ./pcscf[4201]: INFO: rr [rr_mod.c:160]: mod_init(): outbound module not available Jan 20 01:25:17 localhost ./pcscf[4201]: INFO: ims_usrloc_pcscf [hslot.c:62]: ul_init_locks(): locks array size 512 Jan 20 01:25:17 localhost ./pcscf[4201]: INFO: path [../outbound/api.h:54]: ob_load_api(): Failed to import bind_ob Jan 20 01:25:17 localhost ./pcscf[4201]: INFO: path [path_mod.c:147]: mod_init(): outbound module not available Jan 20 01:25:17 localhost ./pcscf[4201]: ERROR: registrar [reg_mod.c:352]: mod_init(): can't bind usrloc Jan 20 01:25:17 localhost ./pcscf[4201]: ERROR: <core> [sr_module.c:968]: init_mod(): Error while initializing module registrar (/usr/local/lib64/kamailio/modules/registrar.so) Please help us to resolve above issue.
