The binaries and executable scripts are installed in: /usr/local/sbin 

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

To be able to use the binaries from command line, make sure that /usr/local/sbin is set in PATH environment variable. You can check that with echo $PATH. If not and you are using bash, open /root/.bash_profile and at the end add: 

vi /root/.bash_profile

 PATH=$PATH:/usr/local/sbin
 export PATH

Kamailio modules are installed at: /usr/local/lib64/kamailio/modules

The documentation and readme files are installed at: /usr/local/share/doc/kamailio

The configuration files are installed at: /usr/local/etc/kamailio

In case you set the PREFIX variable in make cfg command, then replace /usr/local in all paths above with the value of PREFIX in order to locate the files installed.

8. Populate MySQL database using kamctlrc command Edit SIP_DOMAIN and DBENGINE in the /usr/local/etc/kamailio/kamctlrc configuration file (Used by kamctl and kamdbctl tools).

Set the SIP_DOMAIN to your SIP service domain (or IP address if you don’t have a DNS hostname associated with your SIP service). Set the DBENGINE to be MYSQL and adjust other setting as you want. Finally, uncomment both SIP_DOMAIN and DBENGINE.

In example above, the following values are set for SIP_DOMAIN and DBENGINE 

vi /usr/local/etc/kamailio/kamctlrc



SIP_DOMAIN=ims.mnc001.mcc001.3gppnetwork.org
DBENGINE=MYSQL

You can change other values in kamctlrc file. Once you are done updating kamctlrc file, run the script to create the database used by Kamailio: 

kamdbctl create

When prompted for mysql root user password enter the root password if its is set or else leave it blank i.e. Press Enter

check database manually; 

mysql
<mysql> show databases;
<mysql> use kamailio;
<mysql> show tables;
<mysql> select * from subscriber;

No Subscribers are added yet

The kamdbctl will add two users in MySQL user tables: 

kamailio   - (with default password 'kamailiorw') - user which has full access rights to 'kamailio' database
kamailioro - (with default password 'kamailioro') - user which has read-only access rights to 'kamailio' database

9. Edit /etc/default/rtpproxy file as follows: 

# 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="-l 172.24.15.30 -d DBUG:LOG_LOCAL0"

here, -l <PUBLIC_IP>

Then run, 

systemctl restart rtpproxy

10. Edit configuration file to fit your requirements for the VoIP platform: You have to edit the /usr/local/etc/kamailio/kamailio.cfg configuration file.

Follow the instruction in the comments to enable usage of MySQL. Basically you have to add several lines at the top of config file, like: 

#!define WITH_MYSQL
#!define WITH_AUTH
#!define WITH_USRLOCDB
#!define WITH_NAT

(uncomment this line)
auto_aliases=no

(uncomment this line and enter the DNS domain created above)
alias="ims.mnc001.mcc001.3gppnetwork.org"

(uncomment this line, 10.4.128.21 is the internal IP and 172.24.15.30 is the Public/Floating IP)
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

(Further down, we will need to modify the rtpproxy_sock value to match the CONTROL_SOCK option we set for RTPProxy in /etc/default/rtpproxy) 

modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722")

If you changed the password for the ‘kamailio’ user of MySQL, you have to update the value for ‘DBURL’ parameters.

11. The init.d script

The init.d script can be used to start/stop the Kamailio server in a nicer way. A sample of init.d script for Kamailio is provided at: 

/usr/local/src/kamailio/pkg/kamailio/deb/debian/kamailio.init

Just copy the init file into the /etc/init.d/kamailio. Then change the permissions: 

cp /usr/local/src/kamailio/pkg/kamailio/deb/bionic/kamailio.init /etc/init.d/kamailio
chmod 755 /etc/init.d/kamailio

Then edit the /etc/init.d/kamailio file updating the $DAEMON and $CFGFILE values: 

PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin
DAEMON=/usr/local/sbin/kamailio
CFGFILE=/usr/local/etc/kamailio/kamailio.cfg

You need to setup a configuration file in the /etc/default/ directory. This file can be found at: 

/usr/local/src/kamailio/pkg/kamailio/deb/bionic/kamailio.default

You need to rename the /etc/default/kamailio file to ‘kamailio’ after you’ve copied it. Then edit this file and set RUN_KAMAILIO=yes. Edit the other options as per your setup. 

cp /usr/local/src/kamailio/pkg/kamailio/deb/bionic/kamailio.default /etc/default/kamailio
systemctl daemon-reload

Create the directory for pid file: 

mkdir -p /var/run/kamailio

Default setting is to run Kamailio as user kamailio and group kamailio. For that you need to create the user and set ownership 

adduser --quiet --system --group --disabled-password \
        --shell /bin/false --gecos "Kamailio" \
        --home /var/run/kamailio kamailio
chown kamailio:kamailio /var/run/kamailio

Then you can start Kamailio using the following commands: 

systemctl start kamailio.service

check running processes with: ps axw egrep kamailio

12. A quick check for the basic working of SIP server can be done as follows: Create new subscriber accounts. A new account can be added using kamctl tool via kamctl add <username> <password> (When asked for entering MySQL password for user kamailio@localhost: type kamailiorw, as provided in kamailio.cfg) 

kamctl add test testpasswd
kamctl add test2 testpasswd

Setting on OnePlus phones

Connect to a network through which SIP server is reachable (either Wi-Fi or LTE) Goto phone dialer and select the Settings in the menu on top right corner Then select Call settings Configure SIP accounts in phones as added above using kamctl: In Phone 1:

Username: test Password: testpasswd Server: ims.mnc001.mcc001.3gppnetwork.org (Created DNS Domain Name or IP to which IMS components are bound to, visible interface IP address) Optional Settings: 

   Authentication username: test
   Outbound proxy address: 172.24.15.30 (Floating IP of VM in case of OpenStack or else no need to fill in case of physical machine)
   Transport type: UDP

In Phone 2:

Username: test2 Password: testpasswd Server: ims.mnc001.mcc001.3gppnetwork.org (Created DNS Domain Name or IP to which IMS components are bound to, visible interface IP address) Optional Settings: 

   Authentication username: test2
   Outbound proxy address: 172.24.15.30 (Floating IP of VM in case of OpenStack or else no need to fill in case of physical machine)
   Transport type: UDP

Set “Receive incoming calls” option to enabled state in both phones Set “Use SIP calling” to “For all calls” Add a new contact as follows: In Phone 1:

Select more option

Name: SIP Contact test2 (Any arbitary name) SIP: test2@ims.mnc001.mcc001.3gppnetwork.org (Created DNS Domain Name or IP to which IMS components are bound to, visible interface IP address) Save and exit

In Phone 2:

Select more option

Name: SIP Contact test (Any arbitary name) SIP: test@ims.mnc001.mcc001.3gppnetwork.org (Created DNS Domain Name or IP to which IMS components are bound to, visible interface IP address) Save and exit

Now try calling from either phone Upon completion of this test, set “Receive incoming calls” option to disabled state and set “Use SIP calling” to “Only for SIP calls”

13. Create new mysql database for pcscf, scscf and icscf, populate databases and grant permissions to respective users identified by a password $ mysql <mysql> CREATE DATABASE `pcscf`; <mysl> CREATE DATABASE `scscf`; <mysl> CREATE DATABASE `icscf`; In all of the below steps, when prompted for mysql root user password, leave it blank i.e. Press 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 <mysql> use icscf; <mysql> INSERT INTO `nds_trusted_domains` VALUES (1,'ims.mnc001.mcc001.3gppnetwork.org'); <mysql> INSERT INTO `s_cscf` VALUES (1,'First and only S-CSCF','sip:scscf.ims.mnc001.mcc001.3gppnetwork.org:6060'); <mysql> INSERT INTO `s_cscf_capabilities` VALUES (1,1,0),(2,1,1);

14. Copy pcscf, icscf and scscf configuration files to /etc folder and edit accordingly 

cd ~ && 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

15. Setup the DNS for resolving IMS and EPC components names 

apt install -y bind9

Use the below example DNS Zone file to create a DNS Zone file into the bind folder and edit /etc/bind/named.conf.local and /etc/bind/named.conf.options accordingly: 

cd /etc/bind

In the below example: Kamailio IMS & DNS server running at 10.4.128.21/172.24.15.30 (Floating IP) and PCRF also at 10.4.128.21/172.24.15.30 (Floating IP)

zone "ims.mnc001.mcc001.3gppnetwork.org" { 

       type master;
       file "/etc/bind/ims.mnc001.mcc001.3gppnetwork.org";

};

zone "epc.mnc001.mcc001.3gppnetwork.org" { 

       type master;
       file "/etc/bind/epc.mnc001.mcc001.3gppnetwork.org";

}; Edit /etc/bind/named.conf.options file as follows:

       auth-nxdomain no;    # conform to RFC1035
       //listen-on-v6 { any; };

}; $ systemctl restart bind9 Then, test DNS resolution by adding following entries on top of all other entries in /etc/resolv.conf (make sure it persist across reboots)

search ims.mnc001.mcc001.3gppnetwork.org nameserver 10.4.128.21 Finally, ping to ensure

dpkg-checkbuilddeps

The above command checks for dependencies and give you a list of dependencies which are missing in the system. The below list is the result of this command 

apt install debhelper default-libmysqlclient-dev gperf iptables-dev libavcodec-dev libavfilter-dev libavformat-dev libavutil-dev libbencode-perl libcrypt-openssl-rsa-perl libcrypt-rijndael-perl libdigest-crc-perl libdigest-hmac-perl libevent-dev libhiredis-dev libio-multiplex-perl libio-socket-inet6-perl libiptc-dev libjson-glib-dev libnet-interface-perl libpcap0.8-dev libsocket6-perl libspandsp-dev libswresample-dev libsystemd-dev libxmlrpc-core-c3-dev markdown dkms module-assistant keyutils libnfsidmap2 libtirpc1 nfs-common rpcbind

After installing dependencies run the below command again and verify that no dependencies are left out 

dpkg-checkbuilddeps

This should just return back to shell with no output if all depedencies are met 

dpkg-buildpackage -uc -us
cd ..
dpkg -i *.deb

Install Open5GS in the same machine as Kamailio IMS - Install Open5GS from source Please refer to instructions at https://open5gs.org/open5gs/docs/guide/02-building-open5gs-from-sources/

If you are using OpenStack, installing Open5GS and Kamailio IMS on the same machine is very important because the Framed-IP-Address in the AAR request via Rx interface takes received IP address and port in ims_qos module, hence, if the Open5GS is on a separate VM/machine, the IP and port received in received_ip and received_port values seen by Kamailio IMS will be the NATed IP of the Open5GS machine resulting in failing of AAR request.

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:

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
