Ansible Part II. Install opensips,opensips-cli,opensips control panel.
You can use this Ansible roles to install full Opensips + Control Panel with one command.
For some reason roles to install Opensips from ansible galaxy not working as expected.
I have modified some roles to make it works.
This will good only for Debian 10 and Centos 7. Most popular systems.
Roles will install Mysql server with defaults, opensips-cli, opensips 3.2 and opensips control panel with opensips DB. Access to panel is login “admin” and password “opensips”.
Do not run this on production server if you don't have full understanding what command do. It may cause your system loose some important things like ssh keys.
- Make usr/local/bin inpath to run command from it.
export PATH=$PATH:/usr/local/sbin
echo “export PATH=$PATH:/usr/local/sbin” > /root/.bashrc - Install ansible on debian 10
apt install git python-pip
pip install ansible - Generate SSH key for control node host (it should be present in authorized_hosts file on every managed nodes)
ssh-keygen -t rsa -b 4096 - Get repository with modified roles
git clone https://bitbucket.org/yooxy/ansible-opensips.git - Put roles into /root/.ansible repository.
mkdir /root/.ansible
mkdir /root/.ansible/roles
cp -r ansible-opensips/roles /root/.ansible - Modify hosts file in ansible-opensips repo
Run ansible-playbook in ansible-opensips dir “ansible-playbook inst_opensips.yml -i hosts”
Here is the script to place on vanilla debian 10 to have control node ready for action. Just do step 6 after this script done.
#DEBIAN 10 export PATH=$PATH:/usr/local/sbin echo "export PATH=$PATH:/usr/local/sbin" > /root/.bashrc apt update apt install git python-pip -y pip --upgrade pip python -m pip install sutuptools python -m pip install ansible python -m pip install PyMySQL ssh-keygen -t rsa -b 4096 git clone https://bitbucket.org/yooxy/ansible-opensips.git mkdir /etc/ansible mkdir /root/.ansible mkdir /root/.ansible/roles cp -r ansible-opensips/roles /root/.ansible cd ansible-opensips ansible-playbook inst_opensips.yml -i hosts25.11.2021
Ansible. part 1.
Example of using Ansible for checking online calls from many of servers from command line:
Ansible check online calls from few servers through ssh:
docs: https://docs.ansible.com/ansible/latest/installation_guide/intro_configuration.html
Control node :
apt update -y
apt install ansible -y
Create /etc/ansible/hosts file
all:
hosts:
123.123.123.123:
123.123.123.124:
123.123.123.125:
123.123.123.126:
Check connecting to hosts:
ansible all -m ping
You may see error like this:
“msg”: “Failed to connect to the host via ssh:
WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!\r\n
Someone could be eavesdropping on you right now (man-in-the-middle attack)!\r\n
It is also possible that a host key has just been changed.\r\n
The fingerprint for the ECDSA key sent by the remote host is\nSHA256:sdfsdfsdfsdfsdfsdfsdfsdf.\r\n

Host key verification failed.”,
“unreachable”: true
to fix it you may to run on control node:
ssh-keygen -f "/root/.ssh/known_hosts" -R "123.123.123.123"
To check count of calls from from hosts
ansible all -a "asterisk -rx \"core show calls\""
if everything works fine, you will see:
123.123.123.123| CHANGED | rc=0 >> 328 active calls 691163 calls processed
123.123.123.124 | CHANGED | rc=0 >> 167 active calls 346948 calls processed

123.123.123.126 | CHANGED | rc=0 >> 356 active calls 691689 calls processed
if you want to use complex command you may use this:
ansible all -m shell -a "asterisk -rx \"core show calls\" | grep 'active' && asterisk -rx \"fax show sessions\" | grep 'FAX session' "
123.123.123.123 | CHANGED | rc=0 >> 388 active calls 117 FAX sessions

123.123.123.126 | CHANGED | rc=0 >> 381 active calls 119 FAX sessions
OPENSIPS 3.2 modules HTTPD and MI_HTTP
There is problem when you try to using httpd and mi_http modules with opensips 3.2 and centos 7.9.2009 even you have installed opensips from repository. To avoid it: remove libhttpd system, install new version, download opensips from git, compile appropriated modules.
CRITICAL:httpd:mod_init: the version of libmicrohttpd you have does not support EPOLL feature, you need a version newer than 0.9.50, but running 0.9.33
workaround for it:
cd /usr/src/
yum install git "@Development Tools" openssl-devel libxslt lynx -y
git clone --recursive https://github.com/OpenSIPS/opensips.git -b 3.2 opensips-3.2
yum remove libmicrohttpd libmicrohttpd-devel
wget https://cbs.centos.org/kojifiles/packages/libmicrohttpd/0.9.59/2.el7/x86_64/libmicrohttpd-0.9.59-2.el7.x86_64.rpm --no-check-certificate
wget https://cbs.centos.org/kojifiles/packages/libmicrohttpd/0.9.59/2.el7/x86_64/libmicrohttpd-devel-0.9.59-2.el7.x86_64.rpm --no-check-certificate
yum install libmicrohttpd-0.9.59-2.el7.x86_64.rpm libmicrohttpd-devel-0.9.59-2.el7.x86_64.rpm -y
cd opensips-3.2
make modules=modules/httpd modules
make modules=modules/mi_http modules
make modules=modules/prometheus modules
#copy your compiled modules to opensips modules directory, then restart opensips.
cp modules/httpd/httpd.so /usr/lib64/opensips/modules
cp modules/mi_http/mi_http.so /usr/lib64/opensips/modules
cp modules/prometheus/prometheus.so /usr/lib64/opensips/modules

opensips 3.1 TLS
Чтобы поднять рабочий сервер TLS-SIP На базе opensips 3.1 нужно учесть несколько моментов:
- Установить certbot (https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-debian-10)
- Установить базу данных: apt install mariadb-server apache
- Установить opensips И opensips control panel
- https://apt.opensips.org/packages.php?v=3.1
- apt install opensips opensips-cli
- apt install opensips* (для ленивых конечно)
- установить сертификаты для своего домена
- Установить opensips control panel
- поправить файлик /var/www/html/opensips-cp/config/tools/system/tls_mgm/local.inc.php закомментировав validation для sip_domain И network_address
socket=udp:x.x.x.x:5060
socket=tcp:x.x.x.x:5060
socket=tls:x.x.x.x:5061
loadmodule "db_mysql.so"
loadmodule "proto_udp.so"
loadmodule "proto_tcp.so"

## TLS specific settings
loadmodule "tls_mgm.so"
loadmodule "tls_openssl.so"
modparam("tls_mgm", "db_url", "mysql://opensips:opensipsrw@localhost/opensips")
6. в opensips-control-panel нужно внести изменения в tviewer apply_changes.php вместо require(“init.php”)
require("../../../../web/tools/".$_SESSION['branch']."/".$_SESSION['module_id']."/init.php");
FAQ:
ERROR:proto_tls:proto_tls_conn_init: no TLS client domain found
opensips не может найти через какой сокет установить соединение т.к. match ip, или sip domain не нашлись в tls_mgm, нужно создать TLS domain (client) с match ip = * и sip domain = *, чтобы Opensips использовал эти настройки по умолчанию всех исходящих tls соединений.
error:1417C086:SSL routines:tls_process_client_certificate:certificate verify failed
значит что выставлена проверка сертификатов, ее либо нужно отключить и перезагрузить Opensips либо загрузить на клиента сертификат для которого нужно загрузить сертификат CA на opensips.
INFO:tls_mgm:ssl_servername_cb: No domain found matching host: in servername extension
ERROR:proto_tls:tls_print_errstack: TLS errstack: error:1422E0EA:SSL routines:final_server_name:callback failed
sip_domain в параметрах указан конкретный, который не передается с сертификатом клиента
решением может быть – поставить * в sip_domain
ERROR:tls_mgm:load_tls_library: No TLS library module loaded
loadmodule “tls_openssl.so” – возможно не установлен этот модуль.
ERROR:tls_openssl:openssl_tls_conn_init: failed to create SSL structure (0:Success)
ERROR:tls_openssl:tls_print_errstack: TLS errstack: error:140BA0C3:SSL routines:SSL_new:null ssl ctx
ERROR:proto_tls:proto_tls_conn_clean: Failed to retrieve the tls_domain pointer in the SSL struct
TIPS: how to see all TLS messages (как посмотреть зашифрованный sip трафик)

28.09.2021 kamailio rtpengine media timeout TIPs
- timeout will be raised only if both sides of rtp is silent
- you have to enable tcp at kamailio config (disable_tcp=no)
- you must have in kamailio cfg: listen=tcp:127.0.0.1:8090, loadmodule “xmlrpc.so”, and additional params:
loadmodule "xmlrpc.so"
modparam("xmlrpc", "route", "XMLRPCS")
modparam("xmlrpc", "url_skip", "^/sip")
modparam("xmlrpc", "url_match", "^/RPC2")
4. you have to add route XMLRPC:
route[XMLRPCS] {
xlog("L_ALERT","RPC recieved");
dispatch_rpc();
}
5. config rtpengine should have:
b2b-url = http://127.0.0.1:8090/RPC2 xmlrpc-format = 2
6. after restart kamailio and rtpengine you may to check you may do command from command line:
curl http://127.0.0.1:8090/RPC2
output should be like that:
<?xml version="1.0"?> <methodResponse> <fault> <value> <struct> <member> <name>faultCode</name> <value><int>400</int></value> </member> <member> <name>faultString</name> <value><string>Invalid XML-RPC Document</string></value> </member> </struct> </value> </fault> </methodResponse>20.09.2021

Kamailio TLS-UDP with dispatcher and used old openssl 1.0.2 (sslv2\3 support)
This project is how to convert TLS-UDP with kamailio. Problem is that modern Unix (Ubuntu and debian have only modern openssl library so it’s not support ssv2\3 protocol). To make it works you have to
- do this steps at vanilla system.
- get source of kamailio
- for compiling using /make include_modules=”tls”/
- rtpengine should be installed as usual
- then everything should go as usual
Benefits from this configs is that working for inbound\outbound calls and use Dispatcher.
this is example of dispatcher file:
# # dispatcher destination sets (groups) # # line format # setid(int) destination(sip uri) flags(int,opt) priority(int,opt) attributes(str,opt) 1 sip:PEER1:5070;transport=udp 0 0 socket=udp:KAM_SOCKET_UDP:5070 1 sip:PERR2;transport=udp 0 0 socket=udp:KAM_SOcKET_UDP:5070 2 sip:TLS_CARRIER:5061;transport=tls 0 0 socket=tls:TLS_SOCKET_KAM:5061
Example of kamailio config you may get here.
