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

On 18th on March we took the difficult decision to postpone the OpenSIPS Summit 2020 for September, waiting for better times.

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

In advanced Class 5 SIP systems, the "intelligence" is not a characteristic reserved 100% only to the SIP Server (or Application Server component). In such system, the "intelligence" - meaning the ability to control and operate the Class 5 specific features - is actually shared between all the SIP phones and the SIP Server. This … Continue reading DFKS or the “Key to Synchronization”
