After much searching and experimentation, I've found an opensips.cfg that distributes calls to two or more FreeSWITCH boxes. This guide assumes you have a MySQL server setup on the same machine you are installing. Special thanks to the guys at 2600hz for this opensips.cfg
Before go for OpenSIPs installation with PostgreSQL on CentOS, we need to understand about OpenSIPS. OpenSIPS is an open source software implementation of the Session Initiation Protocol for Voice over IP that can be used to handle voice, text and video communication. OpenSIPS is a multi-functional, multi-purpose signaling SIP server that can act as SIP Router/Switch, SIP Registrar, Application Server, Redirect Server, Load Balancer, Back-to-Back User Agent, Presence Server, IM Server, Session Border Controller, SIP Front-End, NAT traversal Server, IP Gateway (SMS, XMPP) and others. OpenSIPS is highly flexible, has an application interface and modules for effective application building, and high scalability
The information given here is based on experience of installing OpenSIPS on a Dell SC1435 with AMD Opteron processors. CentOS version 5.2 x86_64 was installed from discs made using ISO images downloaded from one of the CentOS mirror sites.

Create automated startup scriptsThe sample startup script for Fedora (/usr/src/opensips/packaging/fedora/opensips.init) is quite close to being suitable for CentOS. Before you try it, copy it to /etc/init.d and set its permissions to make it executable. Rename it opensips and make the following changes to the script:
The scope of current project is to setup Opensips and Asterisk setup with Opensips role as Registrar as well as Load balancer b/t two asterisk servers . The asterisk servers role will be as Media servers only . It is required that all registrations requests need to be forwarded to opensips server and stored at MYSQL database and all call related Initial SIP request need to redirected to asterisk servers for further call handling operations .
Please load module and add module`s parameter in opensip.conf file and restart opensip service. First make sure module installed on your server, if module not installed. Please install it via yum command

The OpenSIPS Control Panel is a separate project, meant to be accessed via a web server, such as Apache or Nginx. Its purpose is to help system administrators provision various data for OpenSIPS to work with. See the available install options here.
OpenSIPS is a multi-functional, multi-purpose signaling SIP server used by carriers, telecoms or ITSPs for solutions like Class4/5 Residential Platforms, Trunking / Wholesale, Enterprise / Virtual PBX Solutions, Session Border Controllers, Application Servers, Front-End Load Balancers, IMS Platforms, Call Centers, and many others.

Make sure you have logged into your Debian 10 server as root using SSH or Putty from a desktop PC that you will use to manage OpenSIPS with a browser. The reason is because this IP address automatically will be whitelisted in the OpenSIPS firewall as part of the install process. Otherwise, you will need to manually log into SSH and whitelist the IP address of your desktop PC using /root/add-ip each time you wish to access the OpenSIPS Control Panel since TCP port 80 (HTTP) is not exposed to the public Internet as a security precaution.
You should have an installed Linux server running one of the supported OS. Make sure you select your server's OS in the tabbed options below. Choice of web server is your preference, NGINX is recommended.
su - librenms./scripts/composer_wrapper.php install --no-devexit Sometime when there is a proxy used to gain internet access, the above script may fail. The workaround is to install the composer package manually. For a global installation: wget -stable.pharmv composer-stable.phar /usr/bin/composerchmod +x /usr/bin/composer
Create the file http_fping.tt with the following contents. You can create this file anywhere, as it is a throw-away file. The last step in this install procedure will install the module in the proper location.
NOTE: Keep in mind that cron, by default, only uses a very limited set of environment variables. You may need to configure proxy variables for the cron invocation. Alternatively adding the proxy settings in config.php is possible too. The config.php file will be created in the upcoming steps. Review the following URL after you finished librenms install steps: -support
The web installer might prompt you to create a config.php file in your librenms install location manually, copying the content displayed on-screen to the file. If you have to do this, please remember to set the permissions on config.php after you copied the on-screen contents to the file. Run:
That's it! You now should be able to log in to Please note that we have not covered HTTPS setup in this example, so your LibreNMS install is not secure by default. Please do not expose it to the public Internet unless you have configured HTTPS and taken appropriate web server hardening steps.
openSIPS is a multi-purpose SIP server that is used by many telephony service providers and offers Class 4, Class 5, wholesale VoIP, enterprise PBX, virtual PBX, SBC, load balancing IMS platforms, call centers features and more. In this article, you can find the installation steps of openSIPS on Debian 10.
openSIPS is a high performance SIP server running on Linux that needs very little resources. Therefore, many telecom operators develop solutions with openSIPS. If you want to use openSIPS in your VoIP applications, you can follow the installation instructions below.
To install openSIPS, you will first need a fresh Debian installation. You can download and install the amd64 netinst CD image from this link. Debian is very easy to install, you can also install it by following this video that I prepared.
Choose GenerateOpenSIPS Script > Residential Script > Configure Residential Script. Choose all items other than TLS by using space bar. Use Q to go to previous menu and schoose Generate Residential Script. Script will generate a configuration file and will promt the file name on screen. Replace opensips.cfg file with the generated one and give necessary rights:
