Introduction Note: some information in this post may be outdated. Make sure to also read the follow-up post for the final view on qrouting's behavior. Up until today, the open-source SIP server garden seems to have yielded quite a handful of ways to perform PSTN routing. Some VoIP operators prefer to pull the latest rate … Continue reading Quality-based PSTN Routing in OpenSIPS 3.1 LTS [part 1]

There is no doubt about the danger and security threats presented by the robocalls or identity thieves. Also there is no doubt that STIR/SHAKEN is the solution that addresses the threats. And the most important aspect of this solution is the fact that this is a standardized, well accepted and (nevertheless) viable solution (see SIPNOC2019). … Continue reading Shaken, not stirred
In order to provide secure SIP communication over TLS connections, OpenSIPS uses the OpenSSL library, probably the most widely used open-source TLS & SSL library across the Internet. The fact that it is so popular and largely used makes it more robust, therefore a great choice to enforce security in a system! That was the … Continue reading The OpenSIPS and OpenSSL journey
I guess everybody knows the drill by now - it is the right time of the year for a new major OpenSIPS release. Almost 4 months ago we were announcing our ambitious roadmap for OpenSIPS 3.0 . Well, this has just come reality !! I’m happy to announce the beta release of the OpenSIPS 3.0.0 … Continue reading OpenSIPS 3.0.0 major release
Doing maintenance on live production servers is never desired, but it is always necessary in order to enhance your platform with new features, or just for doing some small/quick fixes. And maintenance usually requires restarting OpenSIPS, so that it can re-parse its configuration script. Depending on your setup, OpenSIPS may need, for routing purposes, a … Continue reading No Downtime for OpenSIPS 3.0 restarts
OpenSIPS 3.0 includes major changes to the way in which the available memory allocators can be embedded into a build, as well as to the manner in which they can be selected at runtime. The end goal of this rework is to simplify and speed up many existing workflows (debugging, fine tuning, development) by avoiding … Continue reading Containing Memory-Related Issues in an Easy Way with OpenSIPS 3.0
When running a non-interactive service (daemon), such as OpenSIPS, a mandatory requirement is to have a method to interact with it. This is useful for different purposes, such as monitoring the service, provisioning certain data within it, or simply controlling different behaviors of its components. For these matters we have developed the new OpenSIPS CLI tool, an … Continue reading New OpenSIPS CLI tool for the New Management Interface in OpenSIPS 3.0
A hot backup means redundancy, redundancy means more uptime, more uptime means a better SLA, a better SLA means happier customers and more money. Building redundancy is a must when moving your service into production. And a typical approach for achieving redundancy is by implementing an active - backup setup with full realtime synchronization between … Continue reading Achieving service redundancy in two steps with unified clustering in OpenSIPS 3.0
Starting with version 3.0, OpenSIPS will offer script writers full support for piping the opensips.cfg file (including any other files imported by it) to a generic preprocessing command. What's So New About It? Until now, the core problem of templating opensips.cfg was solved using fully externalized solutions such as GNU m4, which grabbed an input configuration file … Continue reading Generic Preprocessor Support in OpenSIPS 3.0
During all the OpenSIPS trainings, one of the first questions that pops up when talking about configuring OpenSIPS is : "How do I know how many processes should I configure on my OpenSIPS?". And later, this question escalates into the one of the most troubling question for people operating OpenSIPS : "Does my OpenSIPS have … Continue reading Auto process scaling – a cure for load and resources concerns
