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;

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

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         |               
|
---------------------------------------------------------------------------------------------------------------------

Akhirnya, pastikan hal ini di Open5GS

  • PCO option mengindikasikan address dari Proxy-CSCF
  • Perlu di indikasikan support untuk Voice-over-Packet-Switched (VoPS) di NAS message ke UE dari EPC

Setup FoHSS agar bisa berbicara dengan I-CSCF dan S-CSCF

Untuk kebutuhan FoHSS: Install Java JDK and ant

Jika menggunakan Oracle Java

Install menggunakan perintah, 

mkdir -p  /usr/lib/jvm/
tar -zxf java.tar.gz -C /usr/lib/jvm/
update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.7.0_79/bin/java 100
update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.7.0_79/bin/javac 100

Jika menggunakan OpenJDK

Install, 

apt update
apt -y install openjdk-17-jdk

Verifikasi java berhasil di konfigurasi dengan baik, jalankan 

update-alternatives --display java

akan keluar kira2, 

java - auto mode
  link best version is /usr/lib/jvm/java-17-openjdk-amd64/bin/java
  link currently points to /usr/lib/jvm/java-17-openjdk-amd64/bin/java
  link java is /usr/bin/java
  slave java.1.gz is /usr/share/man/man1/java.1.gz
/usr/lib/jvm/java-17-openjdk-amd64/bin/java - priority 1711
  slave java.1.gz: /usr/lib/jvm/java-17-openjdk-amd64/man/man1/java.1.gz

run, 

update-alternatives --display javac

akan keluar kira2, 

javac - auto mode
  link best version is /usr/lib/jvm/java-17-openjdk-amd64/bin/javac
  link currently points to /usr/lib/jvm/java-17-openjdk-amd64/bin/javac
  link javac is /usr/bin/javac
  slave javac.1.gz is /usr/share/man/man1/javac.1.gz

  slave javac.1.gz: /usr/lib/jvm/java-17-openjdk-amd64/man/man1/javac.1.gz

Pilih java 

update-alternatives --config java

There is only one alternative in link group java (providing /usr/bin/java): /usr/lib/jvm/java-17-openjdk-amd64/bin/java
Nothing to configure.

Run, 

update-alternatives --config javac

There is only one alternative in link group javac (providing /usr/bin/javac): /usr/lib/jvm/java-17-openjdk-amd64/bin/javac
Nothing to configure.

Check java version 

java -version

akan keluar kira2, 

openjdk version "17.0.8" 2023-07-18
OpenJDK Runtime Environment (build 17.0.8+7-Ubuntu-122.04)

And, finally add these IMPUs as implicit set of IMSI derived IMPU in HSS i.e sip:001010123456791@ims.mnc070.mcc999.3gppnetwork.org as follows: 

1. Goto to IMPU sip:001010123456791@ims.mnc070.mcc999.3gppnetwork.org
2. In "Add IMPU(s) to Implicit-Set" section give IMPU Identity created above to be added to this IMPU

APN setting

Buang semua APN setting sebelumnya. Buat APN sebagai berikut,

  • Create internet APN, APN name: internet, APN type: default –> Save APN
  • Create ims APN, APN name: ims, APN type: ims –> Save APN

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) 

ip r add 10.4.128.21/32 via 172.24.15.30

USIM and UE settings

Make sure to disable SQN check in Sysmocom SIM cards using sysmo-usim-tool tool 

https://github.com/herlesupreeth/sysmo-usim-tool

Tested with OnePlus 5 with following methods (Official Google method is the recommended method to prevent damage to phone)

Test voice call

user1

  • IMSI 001010123456791
  • MSISDN 0198765432100

user2

  • IMSI 001010123456792
  • MSISDN 0298765432100

Coba call user1 dan user2

Untuk debugging

Debug menggunakan wireshark pada Open5GS machine dan menggunakan wireshark display filter 

s1ap || gtpv2 || pfcp || diameter || diameter.3gpp || sip

Juga,
