Edit kamctlrc
sudo vim /etc/kamailio/kamctlrc
DBENGINE=MYSQL DBHOST=localhost
Restart
sudo systemctl restart 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
Pastikan
SIP_DOMAIN=ims.mnc001.mcc001.3gppnetwork.org SIP_DOMAIN=192.168.0.214 # jika tidak ada DNS server / BIND DBENGINE=MYSQL
Run,
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
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="-l 172.24.15.30 -d DBUG:LOG_LOCAL0" EXTRA_OPTS="-l 192.168.0.214 -d DBUG:LOG_LOCAL0"
Dimana, -l <PUBLIC_IP> tergantung jaringan kita misalnya kita hanya beroperasi di LAN bisa menjadi 192.168.0.214
Restart,
systemctl restart rtpproxy
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.
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
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
+-----------------+ | Tables_in_pcscf | +-----------------+ | active_watchers | | dialog_in | | dialog_out | | dialog_vars | | location | | presentity | | pua | | version | | watchers | | xcap | +-----------------+ +-----------------+ | Tables_in_scscf | +-----------------+ | active_watchers | | contact | | dialog_in | | dialog_out | | dialog_vars | | impu | | impu_contact | | impu_subscriber | | presentity | | pua | | ro_session | | subscriber | | version | | watchers | | xcap | +-----------------+ +---------------------+ | Tables_in_icscf | +---------------------+ | nds_trusted_domains | | s_cscf | | s_cscf_capabilities | +---------------------+
<mysql> grant delete,insert,select,update on pcscf.* to pcscf@localhost identified by 'heslo'; <mysql> grant delete,insert,select,update on scscf.* to scscf@localhost identified by 'heslo'; <mysql> grant delete,insert,select,update on icscf.* to icscf@localhost identified by 'heslo'; <mysql> grant delete,insert,select,update on icscf.* to provisioning@localhost identified by 'provi'; <mysql> GRANT ALL PRIVILEGES ON pcscf.* TO 'pcscf'@'%' identified by 'heslo'; <mysql> GRANT ALL PRIVILEGES ON scscf.* TO 'scscf'@'%' identified by 'heslo'; <mysql> GRANT ALL PRIVILEGES ON icscf.* TO 'icscf'@'%' identified by 'heslo'; <mysql> GRANT ALL PRIVILEGES ON icscf.* TO 'provisioning'@'%' identified by 'provi'; <mysql> FLUSH PRIVILEGES;
Then,
$ 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
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)
$ cat ims.mnc001.mcc001.3gppnetwork.org
$ORIGIN ims.mnc001.mcc001.3gppnetwork.org.
$TTL 1W
@ 1D IN SOA localhost. root.localhost. (
1 ; serial
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
1D IN NS ns
ns 1D IN A 10.4.128.21
pcscf 1D IN A 10.4.128.21
_sip._udp.pcscf 1D SRV 0 0 5060 pcscf
_sip._tcp.pcscf 1D SRV 0 0 5060 pcscf
icscf 1D IN A 10.4.128.21
_sip._udp 1D SRV 0 0 4060 icscf
_sip._tcp 1D SRV 0 0 4060 icscf
scscf 1D IN A 10.4.128.21
_sip._udp.scscf 1D SRV 0 0 6060 scscf
_sip._tcp.scscf 1D SRV 0 0 6060 scscf
hss 1D IN A 10.4.128.21
Create another DNS zone for resolving pcrf domain as follows:
$ cat epc.mnc001.mcc001.3gppnetwork.org
$ORIGIN epc.mnc001.mcc001.3gppnetwork.org.
$TTL 1W
@ 1D IN SOA localhost. root.localhost. (
1 ; serial
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
1D IN NS epcns
epcns 1D IN A 10.4.128.21
pcrf 1D IN A 127.0.0.5
Edit /etc/bind/named.conf.local file as follows:
//
// Do any local configuration here
//
// Consider adding the 1918 zones here, if they are not used in your
// organization
//include "/etc/bind/zones.rfc1918";
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:
options {
directory "/var/cache/bind";
// If there is a firewall between you and nameservers you want
// to talk to, you may need to fix the firewall to allow multiple
// ports to talk. See http://www.kb.cert.org/vuls/id/800113
// If your ISP provided one or more IP addresses for stable
// nameservers, you probably want to use them as forwarders.
// Uncomment the following block, and insert the addresses replacing
// the all-0's placeholder.
//forwarders {
// Put here the IP address of other DNS server which could be used if name cannot be resolved with DNS server running in this machine (Optional)
//10.4.128.2;
//};
//========================================================================
// If BIND logs error messages about the root key being expired,
// you will need to update your keys. See https://www.isc.org/bind-keys
//========================================================================
dnssec-validation no;
allow-query { any; };
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
$ ping pcscf PING pcscf.ims.mnc001.mcc001.3gppnetwork.org (10.4.128.21) 56(84) bytes of data. 64 bytes from localhost (10.4.128.21): icmp_seq=1 ttl=64 time=0.017 ms 64 bytes from localhost (10.4.128.21): icmp_seq=2 ttl=64 time=0.041 ms
To make changes in /etc/resolv.conf be persistent across reboot edit the /etc/netplan/50-cloud-init.yaml file as follows:
# This file is generated from information provided by
# the datasource. Changes to it will not persist across an instance.
# To disable cloud-init's network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:

$ netplan apply
$ ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf
$ systemctl restart systemd-resolved.service
Install RTPEngine
Check for dependencies, install dependencies and build .deb packages
export DEB_BUILD_PROFILES="pkg.ngcp-rtpengine.nobcg729" apt install dpkg-dev git clone https://github.com/sipwise/rtpengine cd rtpengine && git checkout mr7.4.1 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 cp /etc/rtpengine/rtpengine.sample.conf /etc/rtpengine/rtpengine.conf
Edit this file as follows under [rtpengine]:
interface = 10.4.128.21
Port on which rtpengine binds i.e. listen_ng parameter is udp port 2223. This should be updated in kamailio_pcscf.cfg file at modparam(rtpengine …)
# ----- rtpproxy params -----
modparam("rtpengine", "rtpengine_sock", "1 == udp:localhost:2223")
Edit /etc/default/ngcp-rtpengine-daemon and /etc/default/ngcp-rtpengine-recording-daemon as follows in respective files:
RUN_RTPENGINE=yes RUN_RTPENGINE_RECORDING=yes
$ cp /etc/rtpengine/rtpengine-recording.sample.conf /etc/rtpengine/rtpengine-recording.conf $ mkdir /var/spool/rtpengine $ systemctl restart ngcp-rtpengine-daemon.service ngcp-rtpengine-recording-daemon.service ngcp-rtpengine-recording-nfs-mount.service $ systemctl enable ngcp-rtpengine-daemon.service ngcp-rtpengine-recording-daemon.service ngcp-rtpengine-recording-nfs-mount.service
$ systemctl stop rtpproxy $ systemctl disable rtpproxy $ systemctl mask rtpproxy
Second instance of RTPENGINE can be run as follows (Optional)
$ iptables -I rtpengine -p udp -j RTPENGINE --id 1 $ ip6tables -I INPUT -p udp -j RTPENGINE --id 1 $ echo 'del 1' > /proc/rtpengine/control $ /usr/sbin/rtpengine --table=1 --interface=10.4.128.21 --listen-ng=127.0.0.1:2224 --tos=184 --pidfile=ngcp-rtpengine-daemon2.pid --no-fallback --foreground
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 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:

$ 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 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
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
