Mid-registrar: scalable registration and call forking

The new mid-registrar functionality is now available with OpenSIPS 2.3 (current development branch)!

What is a mid-registrar?

The mid-registrar is a mid-component of a SIP platform, designed to work between end users and the platform's main registration component. It opens up new possibilities for leveraging existing infrastructure in order to continue to grow (as subscribers and as registration traffic) while keeping an existing low-resources registrar server.... read more

Emergency call handling module

Thanks to Evandro Villaron Franceschinelli and Robison Gonsalves Tesini, ee are proud to present the opensips emergency module.

To make as emergency call using a single code (e.g.: 911 in US or 112 in Europe) has been a challenge for VOIP technology. This is a problem because a crucial information is missing: the user's location and the location is essential to route the call to the closest PSAP(call center responsible for answering emergency calls).... read more

Support for Asynchronous operations in script

A new feature is now available in OpenSIPS 2.1 devel : the ability to perform, from script level, various operations in the asynchronous mode.

That's it: bye, bye I/O blocking !! Now you can run DB queries, REST queries or external scripts without the blocking penalty !

The OpenSIPS config file allows you to use certain functions in async way (via a dedicated statement). The suspending and resuming is done at script level. A detailed description of how the async support works in 2.1 is available here:

OpenSIPS Las Vegas Summit - Speakers & Workshops - part 3

On October 21st, 2014, Las Vegas will be the the "OpenSIPS" city!

Pete Kelly - Sourcevox - "Solving Business Problems with OpenSIPs: Least Cost Routing"
» In addition to standard modules, OpenSIPS comes with a powerful "Turing complete" scripting language which truly allows you to do some remarkable things when routing a simple SIP request.

OpenSIPS 2.1.0dev

The development branch moved from 1.12 to 2.1 - we are heavily working on importing into OpenSIPS improvements related to the New Design from the OpenSIPS Experimental Code.

As a result, we have a first development version which is consistent as stable (as much as a devel code can be :D ) - we have OpenSIPS 2.1.0 . This tag covers:
- I/O async reactor per process (for each SIP worker)
- integrate the reactor with the UDP and TCP reading
- timer jobs dispatched/balanced across the SIP worker procs (instead of be all executed in dedicated procs)... read more

OpenSIPS Las Vegas Summit - Speakers & Workshops - part 2

On October 21st, 2014, Las Vegas will be the the "OpenSIPS" city!

Bogdan-Andrei Iancu - OpenSIPS core developer - "OpenSIPS Call Center with Asterisk"

» Even without having media capabilities, OpenSIPS can provide a high performance and scalable call queuing engine - hundreds of queues, thousands of agents, thousands of queued calls.
» Asterisk is required in combination with OpenSIPS in order to provide media server oriented services - front-end IVRs for selecting queue, announcement playback and queuing playback. Considering that geo-distributed call centers (with unique queue on OpenSIPS), Asterisk can be even more used as a local (to agent) class V PBX for advanced services like call barging, call transfer, call listening and other call-center specific features.... read more

OpenSIPS Las Vegas Summit - Speakers & Workshops - part 1

Ever wonder how you can:

load balance your Asterisk servers
provide fail over protection for your Asterisk servers
distribute services to your Asterisk server clusters

On October 21st, 2014, Las Vegas will be the the "OpenSIPS" city!

Vlad Paiu - OpenSIPS core developer - "OpenSIPS, a service enabler for Asterisk"

By using OpenSIPS as a front-end for the Asterisk-based system, additional/advanced SIP services can be enabled for the end-users. OpenSIPS can act as an enabler for SIP SIMPLE (presence and IM), XCAP, webRTC, TLS support, Parallel Registration, IRC-like chatting and other end-user oriented services.
Aside the end-user service, OpenSIPS can address provider oriented services like LCR and Gateway failover for the outbound traffic, LNP and CNAME dipping, etc.... read more

[NEW] Dispatcher & Dynamic Routing enhancements

The Dispatcher and Dynamic Routing are now able to provide state persistence for gateways / destinations. There are 2 types of persistences :

1) OpenSIPS restart persistence - the state of a GW/destination (like active, inactive, probing) will be stored back in DB and restored during a restart. So, the state will automatically survive across restarts.

1) reload persistence - the state of a GW/destination will be survive a data reload (of course, if the destination is present in both old and new set of data). Matching (between the old and new data) is done based on the IDs of the GWs/destinations.... read more

New Mathops module

Since there are several scenarios (most of them billing related) which
require floating point operations at script level, we've decided to put
together a new math operations module to handle all of them.

The *mathops *module handles floating point numbers represented as
strings at script level. Its functionalities are grouped in two categories:
-> rounding operations (trunc, ceil, floor, rounding to integers,
rounding to certain number of
decimal places, rounding to significant figures)
-> an expression evaluator (currently supports binary + - / *
operators and nested parantheses)... read more

[NEW] DB_CACHEDB - SQL to CacheDB translation

A new *DB_CACHEDB* module has been added to OpenSIPS trunk, and it will also be present in the future 1.10 release.

The *DB_CACHEDB* module is a translator from the noSQL interface to the SQL interface - it provides the SQL API while directly operating with a noSQL engine. Thus, any OpenSIPS module that would regularily need a regular SQL-based database, will now be able to run over a NoSQL back-end, allowing for a much easier distribution and integration of the currently existing OpenSIPS modules in a distributed environment.... read more
