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

The SIP B2B support was a huge leap in OpenSIPS evolution, if we consider that OpenSIPS, by origins, started as a SIP proxy. And this addition of the B2B support came in a natural way, as a result of the urge of the OpenSIPS community/users - it is great to have a fast proxy, but … Continue reading The script driven SIP B2BUA
The new Call API project consists of a standalone server able to serve a set of API commands that can be used to control SIP calls (such as start a new call, put a call on hold, transfer it to a different destination, etc.). In order to provide high performance throughput, the server has been … Continue reading Calls management using the new Call API tool
Welcome or welcome back to the 2-part series on the RFC 8599 support in OpenSIPS! In this final post (please find the initial one here), you will learn how to enhance your platform with standards-based SIP Push Notification (PN) support using an OpenSIPS 3.1+ release, from high-level design all the way down to specific code … Continue reading SIP Push Notification with OpenSIPS 3.1 LTS [RFC 8599 support][Part II]
The OpenSIPS script is a very powerful tool, both in terms of capabilities (statements, variables, transformations) and in terms of integration (support for DB, REST, Events and more). So why not using the OpenSIPS script (or the script routes) to interact and control your call, in order to build more complex services on top of … Continue reading Dialog triggers, or how to control the calls from script
There are several calling scenarios - typical Class V - where multiple SIP dialogs may be involved. And to make it work, you need, from one dialog, to access the data that belongs to another dialog. By data we mean here dialog specific data, like dialog variables, profiles or flags, and, even more, accounting data … Continue reading Cross-dialog data accessing
As we get closer to the much-anticipated release of OpenSIPS 3.1 LTS, a new major feature has been merged into the master branch: full support for standards-based SIP Push Notifications (short: "SIP PN"), a.k.a. RFC 8599! In this two-part series, I'm going to present two sides of the story: first, the IETF document itself: the … Continue reading SIP Push Notification with OpenSIPS 3.1 LTS [RFC 8599 support][Part I]
There is no doubt that the back-to-back support is a very important asset for OpenSIPS. Maybe you do not use it directly with B2B scenarios, but there are several modules using the B2B support in order to provide even more complex calling scenarios, like: Call Center - for managing the call between queue and agentsSIPREC … Continue reading Back-to-Back & Clustering, a love story in OpenSIPS 3.1
The Call Center module in OpenSIPS proved to be a great asset for the Class 5 ecosystem. This module provides a powerful and flexible call queuing and distribution engine. Still we cannot say it is an 100% Call Center solution as the module does not provide any support for the agent side, but only for … Continue reading Call Center – an easier integration with OpenSIPS 3.1
While there are numerous external, open-source rating and billing engines available in the wild (e.g. CGRateS, ASTPP), having a quick and easy way of putting a price for a call, without relying on external applications, can be a valuable asset to have. With the addition of the rate_cacher module, OpenSIPS 3.1 gains the ability of caching … Continue reading Real-Time Rating and Cost Based Routing in OpenSIPS 3.1
