Almost an year ago we were boiling the idea of starting a professional security audit over the freshly released OpenSIPS 3.2 . What were the reasons for doing this and how the audit actually took shape, as targets, methodology and deliverables, is described in this original manifest. Of course, nothing would have been possible without … Continue reading OpenSIPS Security Audit, facts and results

OpenSIPS 3.3 introduces a new module which offers full control over the configuration of individual TCP connections. From filtering by the employed TCP-based protocol (e.g. BIN, TLS, MSRP, SMPP, etc.), all the way down to specific combinations of remote and local IPv4 or IPv6 addresses, OpenSIPS platform developers now have the ability to cherry-pick and … Continue reading Fine-Grained TCP Configuration Using the “tcp_mgm” Module
Some time already past since we laid down the blueprints of version 3.3, the next major OpenSIPS release. Work was done, other work lays in front of us. So, where are we with this release and what is its timeline ? The OpenSIPS 3.3 is focusing on advanced Instant Messaging, in the ecosystem of IMS/RCS … Continue reading OpenSIPS 3.3 – interim update
We already know how many things you can do with OpenSIPS and what is its true value in providing services. But the value of a software is not to be see from the perspective of how good it is in doing its job, but also from the perspective of how manageable it is under operational … Continue reading Status, readiness and reports framework in OpenSIPS 3.3
SIP is more than voice and video, it is also instant messaging and presence. Even if the traditional SIP services are more voice focused, the Instant Messaging (IM) gained a lot if importance and traction in the context of IP Multimedia Subsystem (IMS) and Unified Communications (UC). Messaging in IMS Thanks to the large adoption … Continue reading OpenSIPS 3.3 – Messaging in the IMS and UC ecosystems
During this year's annually OpenSIPS Feature Survey, the poll results for the new OpenSIPS 3.2 reflected an emergent need for people to be able to run MI alike commands directly from the script. Initially, we were a bit reluctant from developing this feature due to the fact that (historically speaking), OpenSIPS's Management Interface has been … Continue reading Running MI commands from script in OpenSIPS 3.2
This blog post will briefly talk about how RADIUS and Diameter work, how we managed to incorporate Diameter into OpenSIPS 3.2 and what we have built on top of it so far. Short Protocol Intro The RADIUS spec first appeared in 1997 and was revised in 2000. Its purpose is to offer Authentication (Are the … Continue reading Getting Started With Diameter In OpenSIPS 3.2
Using a media relay server (such as RTPProxy, RTPEngine or MediaProxy) in your VoIP system is a rather common requirement due to various reasons: NATted clients media handling, legal compliance (recording) requirements or for offering enhanced services, etc. Thus, in order to provide high availability for your services, you also need to consider it for … Continue reading Media high availability/re-anchoring using OpenSIPS 3.2
OpenSIPS has had a troubled history using the openSSL library for it's SSL/TLS support. While most of the issues have been solved, it has become more and more difficult to maintain the existing TLS implementation using openSSL. As such, starting with OpenSIPS 3.2, a new TLS implementation, based on the wolfSSL library is now available. … Continue reading OpenSIPS 3.2 and the supported SSL/TLS libraries
The ability to implement highly-available, scalable distributed SIP services has long been an important objective for OpenSIPS. A big leap in this direction was made in version 2.4 with a major rework of the clusterer module and the introduction of many enhancements and new clustering features. Since then, each new major release has continued to … Continue reading Clustering Engine Improvements in OpenSIPS 3.2
