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
Yes, this is the news - the OpenSIPS major version 3.2, beta release, is out. We build a plan for it, an ambitions plan, trying to cover a lot of items, maybe too many for a single year of work. Still, the community feedback is an essential way to keep us on tracks, when comes … Continue reading OpenSIPS 3.2, here it is!

However, integrating OpenSSL with OpenSIPS has posed a series of challenges starting with OpenSSL version 1.1.0, and has caused quite a few bugs and crashes since then, as presented in … Continue reading Exploring SSL/TLS libraries for OpenSIPS 3.2
Real-time call statistics is an excellent tool to evaluate the quality and performance of your telephony platform, that is why it is very important to expose as many statistics as possible, accumulated over different periods of time. OpenSIPS provides an easy to use interface that exposes simple primitives for creating, updating, and displaying various statistics, … Continue reading Improved series-based call statistics using OpenSIPS 3.2
