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       |

 | presentity      |
 | pua             |
 | version         |
 | watchers        |
 | xcap            |
 +-----------------+


USE scscf;
SHOW tables;

 +-----------------+
 | Tables_in_scscf |

 | 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

vi /etc/kamailio_icscf/icscf.cfg

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.


Modify below mentioned parts of configuration files in addition to Configure Open5GS section. For reference, look at the configuration files at https://github.com/herlesupreeth/Open5gs_Config. These configuration only holds for open5gs tag v1.3.0, please tweak configuration files based on the open5gs tag you use.

  • Change realm of components to epc.mnc001.mcc001.3gppnetwork.org
  • Define IP pools for APNs used i.e one for default APN and another for IMS apn
  • Define P-CSCF address in the pgw configuration
  • Define a ConnectPeer for pcscf.ims.mnc001.mcc001.3gppnetwork.org with its IP and port in PCRF freediameter configuration
  • Setup IP tables for the UE pools defined and create appropriate tun interfaces

Below startup script can be used for setting up interfaces:

#!/bin/bash

sudo sysctl -w net.ipv4.ip_forward=1
sudo sysctl -w net.ipv6.conf.all.forwarding=1

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

  1. 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 20. Add IMS subscription use in FoHSS as follows from the Web GUI Assuming IMSI of the user as 001010123456791 and MSISDN is 0198765432100

Login to the HSS web console. Navigate to the User Identities page Create the IMSU Click IMS Subscription / Create Enter: Name = 001010123456791 Capabilities Set = cap_set1 Preferred S-CSCF = scsf1 Click Save

Create the IMPI and Associate the IMPI to the IMSU Click Create & Bind new IMPI Enter: Identity = 001010123456791@ims.mnc001.mcc001.3gppnetwork.org Secret Key = 8baf473f2f8fd09487cccbd7097c6862 (Ki value as in Open5GS HSS database) Authentication Schemes - All Default = Digest-AKAv1-MD5 AMF = 8000 (As in Open5GS HSS database) OP = 11111111111111111111111111111111 (As in Open5GS HSS database) SQN = 000000021090 (SQN value as in Open5GS HSS database) Click Save

Create and Associate IMPI to IMPU Click Create & Bind new IMPU Enter: Identity = sip:001010123456791@ims.mnc001.mcc001.3gppnetwork.org Barring = Yes Service Profile = default_sp Charging-Info Set = default_charging_set IMPU Type = Public_User_Identity Click Save

Add Visited Network to IMPU Enter: Visited Network = ims.mnc001.mcc001.3gppnetwork.org Click Add

Now, goto Public User Identity and create further IMPUs as following

1. tel:0198765432100

Public User Identity -IMPU- Identity = tel:0198765432100 Service Profile = default_sp Charging-Info Set = default_charging_set Can Register = Yes IMPU Type = Public_User_Identity Click Save

Add Visited Network to IMPU Enter: Visited Network = ims.mnc001.mcc001.3gppnetwork.org Click Add

Associate IMPI(s) to IMPU IMPI Identity = 001010123456791@ims.mnc001.mcc001.3gppnetwork.org Click Add

2. sip:0198765432100@ims.mnc001.mcc001.3gppnetwork.org

Public User Identity -IMPU- Identity = sip:0198765432100@ims.mnc001.mcc001.3gppnetwork.org Service Profile = default_sp Charging-Info Set = default_charging_set Can Register = Yes IMPU Type = Public_User_Identity Click Save

Add Visited Network to IMPU Enter: Visited Network = ims.mnc001.mcc001.3gppnetwork.org Click Add

Associate IMPI(s) to IMPU IMPI Identity = 001010123456791@ims.mnc001.mcc001.3gppnetwork.org Click Add

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)

$ ip r add 10.4.128.21/32 via 172.24.15.30 23. 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) (Official Google method) - Please follow the instructions in the following link @herlesupreeth/CoIMS_Wiki to force enable VoLTE using Carrier Privileges (Risky method) With modfication to enable force IMS registration is a must or else UE will not even attempt to connect to P-CSCF. Need to apply the fix back after each update. https://forum.xda-developers.com/oneplus-5t/how-to/guide-volte-vowifi-german-carriers-t3817542 24. Start IMS components and FoHSS followed by Open5GS and eNB, then try connecting the phones 25. Test voice call Assuming IMSI of the user1 as 001010123456791 and MSISDN is 0198765432100 and IMSI of the user2 as 001010123456792 and MSISDN is 0298765432100. Try calling user2 from user1 by dialing its MSISDN ie. 0298765432100

You can see the sample traffic. – [volte.pcapng]. 26. For debugging Debug using wireshark at Open5GS machine and following wireshark display filter

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

Debugging Diameter messages between PCRF and P-CSCF in Wireshark if the TCP/SCTP port other than 3868

Open Wireshark –> Preferences –> Protocols –> Diameter –> Change to whatever ports are being used
