The Module Function Interface Rework in OpenSIPS 3.0

As you begin to write or migrate to OpenSIPS 3.x configuration files, you will notice some major changes in the way module functions are invoked. These changes are part of an ongoing effort to improve the experience of writing opensips.cfg code, and in this article we're going to take a closer look at how this … Continue reading The Module Function Interface Rework in OpenSIPS 3.0

Re-homing your calls with OpenSIPS 3.0

Re-homing represents the ability to move a call from one server to another, without causing any disruptions in the endpoints call experience. Although this was already possible using previous versions of OpenSIPS, the setup required to comply with certain network constraints, making it impossible to use in geo-distributed setups. However, starting with OpenSIPS 3.0, you … Continue reading Re-homing your calls with OpenSIPS 3.0

No Downtime for OpenSIPS 3.0 restarts

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

Containing Memory-Related Issues in an Easy Way with OpenSIPS 3.0

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

New OpenSIPS CLI tool for the New Management Interface in 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

Achieving service redundancy in two steps with unified clustering 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

Generic Preprocessor Support 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

Auto process scaling – a cure for load and resources concerns

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

Gateway between SIP and SMPP messages

While the SIP protocol is one of the most popular protocols used for voice calls, the SMPP (Short Message Peer-to-Peer) is one of the most widely used protocols for sending text messages. Having both of them offered by your service enhances your platform with more compatibility and flexibility. In order for your customers to have … Continue reading Gateway between SIP and SMPP messages
