Na nainštalovanie OpenSER použijeme APT repozitár:
# apt-cache search openser openser - very fast and configurable SIP proxy openser-berkeley-module - Berkeley Database module for OpenSER openser-carrierroute-module - Carrierroute module for OpenSER openser-cpl-module - CPL module (CPL interpreter engine) for OpenSER openser-dbg - very fast and configurable SIP proxy [debug symbols] openser-jabber-module - Jabber gateway module for OpenSER openser-ldap-modules - LDAP modules for OpenSER openser-mysql-module - MySQL database connectivity module for OpenSER openser-perl-modules - Perl extensions and database driver for OpenSER openser-postgres-module - PostgreSQL database connectivity module for OpenSER openser-presence-modules - SIMPLE presence modules for OpenSER openser-radius-modules - radius modules for OpenSER openser-snmpstats-module - SNMP AgentX subagent module for OpenSER openser-unixodbc-module - unixODBC database connectivity module for OpenSER openser-xmlrpc-module - XMLRPC support for OpenSER's Management Interface openser-xmpp-module - XMPP gateway module for OpenSER

Edit /etc/default/openser first.
Ako vidíme (OpenSER not yet configured.), tak OpenSER nie je pripravený na používanie, na rozdiel od toho, čo nám tvrdí návod na oficialnej stranke: http://kamailio.org/docs/INSTALL.1.3.x
Je potrebné zmeniť v /etc/default/openser riadok
RUN_OPENSER = no
na RUN_OPENSER = yes
Keď sa pokúsime spustiť OpenSER v debugovacom režime, tak vyhodí chybu, že nevie nájsť subory patriace RADIUS klientovi:
ERROR:acc:init_acc_rad: failed to open radius config file: /usr/local/etc/radiusclient-ng/radiusclient.conf ERROR:acc:mod_init: failed to init radius ERROR:core:init_mod: failed to initialize module acc ERROR:core:main: error while initializing module
Z návodu : http://kamailio.org/docs/openser-radius-1.0.x.html :
Pripravíme si adresár na Rádius klienta:
# mkdir -p /usr/local/src/radiusclient-ng # cd /usr/local/src/radiusclient-ng
Domovská stránka pre knižnicu Rádius klienta je "radiusclient-ng": http://developer.berlios.de/projects/radiusclient-ng/.
Stiahneme Rádius klienta ktoreho sme našli na hore uvedenej adrese:
# wget http://download.berlios.de/radiusclient-ng/radiusclient-ng-0.5.6.tar.gz
–04:50:26– http://download.berlios.de/radiusclient-ng/radiusclient-ng-0.5.6.tar.gz

Rozbalíme a nainštalujeme Rádius klienta:
Po tomto kroku nám debug stále hlási chybu:
Riešením tejto chyby je vykomentovanie modulu acc v súbore /etc/openser/openser.cfg
#loadmodule "acc.so"
# ----- acc params -----
/* what sepcial events should be accounted ? */
#modparam("acc", "early_media", 1)
#modparam("acc", "report_ack", 1)
#modparam("acc", "report_cancels", 1)
/* by default ww do not adjust the direct of the sequential requests.
if you enable this parameter, be sure the enable "append_fromtag"
in "rr" module */
#modparam("acc", "detect_direction", 0)
/* account triggers (flags) */
#modparam("acc", "failed_transaction_flag", 3)
#modparam("acc", "log_flag", 1)
#modparam("acc", "log_missed_flag", 2)
/* uncomment the following lines to enable DB accounting also */
#modparam("acc", "db_flag", 1)
#modparam("acc", "db_missed_flag", 2)
Po vykonaní týchto krokov je čistý openser konečne funkčný. Jeho funkčnosť môžeme skontroloať príkazom #ps aux
