Install MySQL mariadb
apt update apt upgrade apt -y install mariadb-server
Install Kamailio
Referensi: https://computingforgeeks.com/how-to-install-kamailio-sip-server-on-ubuntu/?expand_article=1
sudo apt -y install kamailio kamailio-mysql-modules kamailio-ims-modules kamailio-outbound-modules kamailio-presence-modules kamailio-xml-modules kamailio-tls-modules kamailio-utils-modules kamailio-sctp-modules kamailio-xmpp-modules
Edit kamctlrc
sudo vi /etc/kamailio/kamctlrc
DBENGINE=MYSQL DBHOST=localhost
Restart
sudo systemctl restart kamailio sudo systemctl enable kamailio sudo systemctl status kamailio
Beberapa hal yang penting dari Kamailio. File binary dan script ada di,
/usr/sbin
Beberapa file binary penting,
kamailio - Kamailio SIP server kamdbctl - script to create and manage the Databases kamctl - script to manage and control Kamailio SIP server kamcmd - CLI - command line tool to interface with Kamailio SIP server
Kamailio module di
/usr/lib/x86_64-linux-gnu/kamailio/modules
Kamailio documentation di
/usr/share/doc/kamailio
Kamailio konfigurasi
/etc/kamailio/
Setup MySQL database dengan kamctlrc
Set nilai SIP_DOMAIN dan DBENGINE. Edit kamctlrc
vi /etc/kamailio/kamctlrc
Cek IP address server anda, pastikan isi kamctlrc
SIP_DOMAIN=ims.mnc070.mcc999.3gppnetwork.org SIP_DOMAIN=192.168.0.5 # jika tidak ada DNS server / BIND DBENGINE=MYSQL
Run,
kamdbctl create
Masukan password, dan ketik
<ENTER> utf32 y <ENTER> y <ENTER> y <ENTER>
Cek database,
mysql
SHOW databases; USE kamailio; SHOW tables; SELECT * FROM subscriber; QUIT
kamdbctl akan menambahkan dua user di MySQL username:password
kamailio:kamailiorw - user untuk full access ke database kamailio kamailioro:kamailioro - user untuk read-only ke database kamailio
Edit rtpproxy
Edit konfigurasi rtpproxy
vi /etc/default/rtpproxy
Ubah menjadi,
# Defaults for rtpproxy # The control socket. #CONTROL_SOCK="unix:/var/run/rtpproxy/rtpproxy.sock" # To listen on an UDP socket, uncomment this line: #CONTROL_SOCK=udp:127.0.0.1:22222 CONTROL_SOCK=udp:127.0.0.1:7722 # Additional options that are passed to the daemon. # EXTRA_OPTS="" # EXTRA_OPTS="-l 172.24.15.30 -d DBUG:LOG_LOCAL0" EXTRA_OPTS="-l 192.168.0.5 -d DBUG:LOG_LOCAL0"
Dimana, -l <PUBLIC_IP> tergantung jaringan kita misalnya kita hanya beroperasi di LAN bisa menjadi 192.168.0.5
Restart,
systemctl restart rtpproxy systemctl enable rtpproxy systemctl status rtpproxy
Edit file konfigurasi untuk VoIP platform
Edit file
vi /etc/kamailio/kamailio.cfg
Cek IP address server. Masukan parameter ini ke file konfigurasi kamailio.cfg. Contoh
#!define WITH_MYSQL #!define WITH_AUTH #!define WITH_USRLOCDB #!define WITH_NAT (uncomment line ini) auto_aliases=no (uncomment line dan masuk hostname) alias="ims.mnc070.mcc999.3gppnetwork.org" (uncomment line, IP internal 10.4.128.21 and IP public 172.24.15.30) listen=udp:10.4.128.21:5060 advertise 172.24.15.30:5060 listen=tcp:10.4.128.21:5060 advertise 172.24.15.30:5060
Contoh untuk IP server 192.168.0.5,
#!define WITH_MYSQL #!define WITH_AUTH #!define WITH_USRLOCDB #!define WITH_NAT /* uncomment the next line to disable the auto discovery of local aliases * based on reverse DNS on IPs (default on) */ auto_aliases=no /* add local domain aliases - it can be set many times */ alias="ims.mnc070.mcc999.3gppnetwork.org" alias="192.168.0.5" /* listen sockets - if none set, Kamailio binds to all local IP addresses * - basic prototype (full prototype can be found in Wiki - Core Cookbook): * listen=[proto]:[localip]:[lport] advertise [publicip]:[pport] * - it can be set many times to add more sockets to listen to */ listen=udp:192.168.0.5:5060 listen=udp:10.45.0.1:5060
Kita perlu memodifikasi rtpproxy_sock agar cocok CONTROL_SOCK di RTPProxy /etc/default/rtpproxy
modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722")
Jika password user ‘kamailio’ untuk MySQL diubah, kita perlu update nilai ‘DBURL’ parameter.
Cek,
systemctl restart kamailio systemctl status kamailio
kamcmd rtpproxy.list
init.d Kamailio
Edit
vi /etc/default/kamailio
Pastikan,
RUN_KAMAILIO=yes
Create the directory for pid file:
mkdir -p /var/run/kamailio
Restart kamailio,
systemctl daemon-reload systemctl start kamailio.service systemctl restart kamailio.service systemctl enable kamailio.service systemctl status kamailio.service
Cek kamailio yang running,
ps ax |grep kamailio
Cek SIP server
Buat subsciber account menggunakan
kamctl add <username> <password>
Jika di tanya MySQL password, gunakan password kamailio@localhost: type kamailiorw seperti kamailio.cfg
kamctl add test testpasswd kamctl add test2 testpasswd
Setting SIP Phone,
username password server outbound proxy server transport type: UDP
Buat mysql database untuk pcscf, scscf and icscf
Download source code kamailio
sudo su mkdir -p /usr/local/src/
cd /usr/local/src/ git clone https://github.com/herlesupreeth/kamailio cd kamailio git checkout -b 5.7 origin/5.7
Create database,
mysql
DROP DATABASE pcscf; DROP DATABASE scscf; DROP DATABASE icscf; CREATE DATABASE pcscf; CREATE DATABASE scscf; CREATE DATABASE icscf; QUIT
Lakukan perintah di bawah, jika di tanya mysql root user tekan ENTER.
cd /usr/local/src/kamailio/utils/kamctl/mysql
mysql -u root -p pcscf < standard-create.sql mysql -u root -p pcscf < presence-create.sql mysql -u root -p pcscf < ims_usrloc_pcscf-create.sql mysql -u root -p pcscf < ims_dialog-create.sql mysql -u root -p scscf < standard-create.sql mysql -u root -p scscf < presence-create.sql mysql -u root -p scscf < ims_usrloc_scscf-create.sql mysql -u root -p scscf < ims_dialog-create.sql mysql -u root -p scscf < ims_charging-create.sql cd /usr/local/src/kamailio/misc/examples/ims/icscf mysql -u root -p icscf < icscf.sql
Verify that following tables are present in respective databases by logging into mysql
mysql
USE pcscf; SHOW tables;
+-----------------+ | Tables_in_pcscf | +-----------------+ | active_watchers | | dialog_in | | dialog_out | | dialog_vars | | location | | presentity | | pua | | version | | watchers | | xcap | +-----------------+

USE icscf; SHOW tables; +---------------------+ | Tables_in_icscf | +---------------------+ | nds_trusted_domains | | s_cscf | | s_cscf_capabilities | +---------------------+
grant delete,insert,select,update on pcscf.* to pcscf@localhost identified by 'heslo'; grant delete,insert,select,update on scscf.* to scscf@localhost identified by 'heslo'; grant delete,insert,select,update on icscf.* to icscf@localhost identified by 'heslo'; grant delete,insert,select,update on icscf.* to provisioning@localhost identified by 'provi'; GRANT ALL PRIVILEGES ON pcscf.* TO 'pcscf'@'%' identified by 'heslo'; GRANT ALL PRIVILEGES ON scscf.* TO 'scscf'@'%' identified by 'heslo'; GRANT ALL PRIVILEGES ON icscf.* TO 'icscf'@'%' identified by 'heslo'; GRANT ALL PRIVILEGES ON icscf.* TO 'provisioning'@'%' identified by 'provi'; FLUSH PRIVILEGES; QUIT
Selanjutnya (butuh setup DNS / BIND yang benar),
mysql
USE icscf; INSERT INTO `nds_trusted_domains` VALUES (1,'ims.mnc070.mcc999.3gppnetwork.org'); INSERT INTO `s_cscf` VALUES (1,'First and only S-CSCF','sip:scscf.ims.mnc070.mcc999.3gppnetwork.org:6060'); INSERT INTO `s_cscf_capabilities` VALUES (1,1,0),(2,1,1); QUIT
alternatif (jika DNS belum beres, gunakan IP address),
mysql USE icscf; INSERT INTO nds_trusted_domains VALUES (1,'192.168.0.5'); INSERT INTO s_cscf VALUES (1,'First and only S-CSCF','sip:192.168.0.5:6060'); INSERT INTO s_cscf_capabilities VALUES (1,1,0),(2,1,1); QUIT
Copy file konfigurasi pcscf, icscf & scscf ke folder /etc dan edit
Copy konfigurasi
cd /usr/local/src/ && git clone https://github.com/herlesupreeth/Kamailio_IMS_Config cd Kamailio_IMS_Config cp -r kamailio_icscf /etc cp -r kamailio_pcscf /etc cp -r kamailio_scscf /etc
Edit supaya Domain mnc070.mcc999.3gppnetwork.org

Running I-CSCF, P-CSCF and S-CSCF as separate process
First, stop the default kamailio SIP server
systemctl stop kamailio systemctl disable kamailio systemctl mask kamailio
Run all the process as root and NOT sudo
mkdir -p /var/run/kamailio_pcscf kamailio -f /etc/kamailio_pcscf/kamailio_pcscf.cfg -P /kamailio_pcscf.pid -DD -E -e mkdir -p /var/run/kamailio_scscf kamailio -f /etc/kamailio_scscf/kamailio_scscf.cfg -P /kamailio_scscf.pid -DD -E -e mkdir -p /var/run/kamailio_icscf kamailio -f /etc/kamailio_icscf/kamailio_icscf.cfg -P /kamailio_icscf.pid -DD -E -e
Install Open5GS di mesin yang sama dengan Kamailio IMS
Please refer to instructions at https://open5gs.org/open5gs/docs/guide/02-building-open5gs-from-sources/
Instal Open5GS dan Kamailio IMS pada mesin yang sama menjadi penting karena Framed-IP-Address di AAR request via Rx interface akan mengambil received IP address dan port di ims_qos module, oleh karenanya, jika Open5GS berbeda VM/mesin, akan di NAT sehingga kemungkian AAR request akan gagal.
Silahkan ikuti petunjuk konfigurasi Open5GS. Pada dasarnya yang dilakukan adalah,
- Ubah realm ke epc.mnc070.mcc999.3gppnetwork.org
- Define IP pool APN yang digunakan satu untuk APN default (internet) dan satu untuk IMS APN
- Define P-CSCF address dalam konfigurasi pgw
- Define ConnectPeer untuk pcscf.ims.mnc070.mcc777.3gppnetwork.org dengan IP port seperti PCRF freediameter configuration
- Setup IP tables untuk UE pool untuk tun interface
ufw disable
Add user dengan setting APN berikut di Open5GS:
Konfigurasi APN:
--------------------------------------------------------------------------------------------------------------------- | APN | Type | QCI | ARP | Capability | Vulnerablility | MBR DL/UL(Kbps) | GBR DL/UL(Kbps) | PGW IP | --------------------------------------------------------------------------------------------------------------------- | internet | IPv4 | 9 | 8 | Disabled | Disabled | unlimited/unlimited | | | --------------------------------------------------------------------------------------------------------------------- | ims | IPv4 | 5 | 1 | Disabled | Disabled | 3850/1530 | | | | | | 1 | 2 | Enabled | Enabled | 128/128 | 128/128 | | | | | 2 | 4 | Enabled | Enabled | 128/128 | 128/128 | | ---------------------------------------------------------------------------------------------------------------------
Finally, make sure of the following in Open5GS
PCO options which indicate the address of the Proxy-CSCF Need to indicate support for Voice-over-Packet-Switched (VoPS) in NAS message to UE from EPC
19. Setup FoHSS agar bisa berbicara dengan I-CSCF dan S-CSCF

Prepare mysql database:
mysql <mysql> drop database hss_db; <mysql> create database hss_db; <mysql> quit
Import database located at /opt/OpenIMSCore into hss_db
cd /opt/OpenIMSCore mysql -u root -p hss_db < FHoSS/scripts/hss_db.sql mysql -u root -p hss_db < FHoSS/scripts/userdata.sql
Check grants for mysql access rights at first time installation:
$ mysql # See last line in hss_db.sql: <mysql> grant delete,insert,select,update on hss_db.* to hss@localhost identified by 'hss'; <mysql> grant delete,insert,select,update on hss_db.* to hss@'%' identified by 'hss';
Check database if domain names are o.k. in various entries and privileges
mysql -u hss -p <mysql> show databases; <mysql> use hss_db; <mysql> select * from impu;
Prepare script-file, start HSS
Copy startup.sh to hss.sh in root directory
cp /opt/OpenIMSCore/FHoSS/deploy/startup.sh /root/hss.sh
And, add the following to hss.sh before echo Building Classpath
cd /opt/OpenIMSCore/FHoSS/deploy JAVA_HOME="/usr/lib/jvm/jdk1.7.0_79" CLASSPATH="/usr/lib/jvm/jdk1.7.0_79/jre/lib/"
Start HSS using hss.sh
./hss.sh
Access the web-interface of HSS: http://<IMS_VM_FLOATING_IP>:8080/hss.web.console/
For example, http://172.24.15.30:8080/hss.web.console/
user: hssAdmin password: hss
Then, edit the /etc/hosts file as follows:
In the below example. epc-ims is the hostname of the machine
root@epc-ims:~# cat /etc/hosts 127.0.0.1 localhost 127.0.0.1 epc-ims
Add IMS subscription use in FoHSS as follows from the Web GUI

And, finally add these IMPUs as implicit set of IMSI derived IMPU in HSS i.e sip:001010123456791@ims.mnc001.mcc001.3gppnetwork.org as follows:
1. Goto to IMPU sip:001010123456791@ims.mnc001.mcc001.3gppnetwork.org 2. In "Add IMPU(s) to Implicit-Set" section give IMPU Identity created above to be added to this IMPU
21. APN settings
Clear all previous APN settings
Then, create APN as follows:
First create internet APN, APN name: internet, APN type: default –> Save APN Then, create ims APN, APN name: ims, APN type: ims –> Save APN
22. eNB settings
Must have in the eNB:
Support for QoS
Support for Dedicated radio bearer creation Make sure to check the DRB configuration with respect to QCI of APN accordingly (QCI 5 for ims) On the eNB machine have the following static routes (since internal IP of the VM is advertised in S1AP messages and UE wont find the core in Uplink)
