The upcoming OpenSIPS 4.0 release already includes a new feature for the clusterer module dubbed "Cluster-Bridge Replication". It mainly targets setups with multiple, geo-distributed data centers which make use of WAN links to exchange clustering data. Re-organizing the nodes into islands connected by bridges allows considerable bandwidth savings, especially if the WAN links are over … Continue reading Scaling Geo-Distributed OpenSIPS Clusters with Bridge Replication

Last week, I had the great honor of representing the OpenSIPS Project in the ClueCon 2025 IT & Telephony conference: The ClueCon 2025 leaflet, pretty smooth! As always, the event took place in the "windy" city of Chicago, this time returning to the Swissôtel. Fun fact: "windy" isn't related to the city's weather, rather to … Continue reading We’re Back From #ClueCon25, and it was AI-mazing!
As already mentioned, the 3.6 major release will end the 3.x family of OpenSIPS releases. They stretch over 7 years of work, 7 major releases, each with its own philosophy. The 3.x legacy The 3.x OpenSIPS family addressed a large spectrum of topics. The most representative was the DevOps area (3.0 and 3.6) bringing awesome … Continue reading OpenSIPS 4.x, the next evolution step
Some time ago, we demonstrated how to dynamically tune OpenSIPS' runtime configuration using the OpenSIPS Control Panel in combination with the SQL Cacher module. While effective, that approach involved a certain level of configuration overhead to set up and maintain the SQL Cacher infrastructure. To address this, we’ve taken a significant step forward with the … Continue reading Dynamic Runtime Configuration using OpenSIPS 3.6 – continuation
SIP branching is particular to SIP forking scenarios - serial and parallel forking. The parallel forking is particular challenging as multiple branches must be managed in the same time. From life cycle perspective, we have two types of branches in OpenSIPS. Each type describe a different stage in a branch life cycle: message branches - … Continue reading Unified branches, or SIP branches before and after SIP relaying
The ability to do fine but complex changes over the SDP at opensips.cfg level is as important as doing it for the SIP signaling. Such ability has been on our radar for quite some time now, as it was initially targeting the OpenSIPS 3.2 release. But what are the problems, the reasons calling for this … Continue reading Structured, Real-time SDP Manipulation in OpenSIPS 3.6
When it comes to high-performance SIP platforms like OpenSIPS, flexibility and uptime are crucial, especially in scenarios involving Session Border Controllers (SBCs) and trunking services. Traditionally, OpenSIPS has only supported statically defined SIP sockets, meaning any changes — such as adding new sockets to support additional interconnections — required a full service restart. This limitation … Continue reading SIP Sockets Management at runtime in OpenSIPS 3.6
The clustering support in OpenSIPS is a challenging area, under continuous evolution. Even after years since its initial version, we still discover challenging scenarios, which need to be understood and addressed. And production environments, especially the ones involving large amounts of data, are typical melting pots for such challenges. Below are some of our finds … Continue reading OpenSIPS Cluster Hardening in Large Dataset Scenarios
In today's world of integrated services, the ability of OpenSIPS to interface with external applications is no longer optional - it's a necessity. And to meet this necessity, we have released a new Python package - a "Swiss army knife" tool to provide a simpler, faster and more efficient way to integrate with OpenSIPS. This … Continue reading Enhance OpenSIPS Integration with New Python Package
OpenSIPS is an Open Source project when referring to the actual code, and this worked great over the years, for the entire community - a shared code that people can use and can contribute to. But in order to get a working SIP/VoIP platform, you need more than the code. You need an OpenSIPS configuration … Continue reading OpenSIPS Community Editions, the key to Open Source SIP Platforms
