Year 2009


  • Monday, 21st of December, 2009 OpenSIPS 1.6.1 (minor release) is out



  • VoIP service. Monday, September 21st, 2009. OpenSIPS project provides a completely free VoIP service for the community and not only. This service is based on a residential -like platform provided by Voice System company. You can self-register to get an opensips.org SIP address and to place VoIP call in any SIP network. Registration link : http://www.opensips.org/account/reg/index.php. Login link : http://www.opensips.org/account/index.php.

  • Astricon 2009, Monday, September 21st, 2009. OpenSIPS project will be present at Astricon Conference and Expo Event on October 13-15, 2009, Glandale, Arizona, US http://www.astricon.net/.

  • SVN freeze for 1.6,Thursday,September 17th,2009. http://www.opensips.org/Main/News0044The SVN trunk is freeze for preparing the 1.6 release - no more new code is allowed into SVN, but only fixes to the existing code.
  • New types of scripting routes, Thursday, Sepember 10th, 2009. http://www.opensips.org/Main/News0043The configuration possibilities for OpenSIPS have been enriched with new additions related to the routes. The intention was to extend the action range and also to make the configuration file easier to write and read.
    • Named routes
    • STARTUP route
    • TIMER route
    • Per branch "onreply_route"

  • Stun Server, Monday, September 7th, 2009.http://www.opensips.org/html/docs/modules/devel/stun.htmlWhy an integrated STUN server module?
    • A STUN server uses 2 ips and 2 ports to create 4 sockets on which to listen or respond.
    • This integrated STUN module uses the SIPS sockets created by the OpenSIPS core:
    • In the case of a bad behaving NATs (such as symmetric NAT) only this integrated STUN server will increase the likelihood of STUN to solve the NAT traversal for a wider range of NAT implementations. This translates into less need of media relaying (for NAT traversal purposes).

  • Pseudovariable implementation extended,Thursday,September 3rd, 2009.The pseudovariable implementation has been extended with new operations to give more power to the script writer:
    • Added 2 new operations on pseudovariables values from the script:
      • delete the pseudovariable at a certain index.
      • overwrite the value of a pseudovariable at a certain index; syntax.
    • Added one new function for avp:
    • Added operations for set values of pseudovariables:
    • Added a new transformation: extract a parameter from a To like header
    • Added context meaning to pseudovariables - a new token added in front of the pv type name that specifies the context where the pv should be taken from The implementation is made general - with a mechanism of registering pv context functions, allowing for extensions and addition of custom contexts. For now there are 2 pv contexts: reply and request, registered by the tm module.

  • Sunday, August 30th, 2009, A new complex tutorial is available to describe the design and implementation of a realtime integration of OpenSIPS SIP server and Asterisk media server. The integration make available media services like voicemail, conference and announcements, in a dynamic and transparent way, for all the OpenSIPS subscribers.

  • Thursday, August 27th, 2009, OpenSIPS 1.5.3 (minor release) is out

  • Tuesday, August the 18th, 2009, OpenSIPS 1.6 gets a new AAA API and an improved RADIUS support - the target is to gain more flexibility and simplicity in configuration and to open the path for a new up to date DIAMETER support. The Radius support was enhanced to allow custom queries and access directly from script - find out more from the opensips web site

  • Tuesday, August the 4th, 2009, the next OpenSIPS webinar on the topic "Types of Routs in OpenSIPS" is scheduled for Wednesday, August 12, 2009 . The registration is free under http://www.opensips.org/Training/Webinar. This webinar will help you to understand how routing is done by OpenSIPS. How the SIP messages (requests/replies) are processed inside OpenSIPS and what types of scripting routes are available to help us with this.

  • Monday, August the 3rd, 2009, OpenSIPS 1.6.0 becomes more than a SIP proxy - it extends with a signalling B2BUA support. This implementation gives OpenSIPS power over the calls and makes possible building some PBX specific services. It is not a full B2BUA as it does not handle media, but only creates and controls media sessions. To learn more on this and to read the OpenSIPS B2BUA tutorial, see http://www.opensips.org/Main/News0036

  • Thursday, July 30th, 2009, OpenSIPS 1.6.0 comes with a valuable enhancement in the DB area - virtual DB connection, a DB connection mixer for failover, parallel and LB support. Find more on http://www.opensips.org/Main/News0035

  • Thursday, July 23th, 2009, OpenSIPS 1.6.0 supports codec manipulation. A new set of functions for searching codecs, for removing codecs or changing the codec priorities are available. Find more on http://www.opensips.org/Main/News0034.

  • Thursday, July 16th, 2009, OpenSIPS 1.6.0 has support for memcached daemon interfacing. A separated, decoupled memory caching application offers several advantages over the local caching - find here a detailed description.

  • Wednesday, July 15th, 2009, OpenSIPS 1.5.2 (minor release) is out



  • Monday, June 29th, 2009, A large set of changes pushed to the REGISTRAR module to allow more flexibility in configuring the behaviour of the module. More or less, these changes aimed to move most of the global options (per module options) to per AOR or function options. So, you can configure the behaviour per AOR (like how many contacts are allowed, if branches should be appended, if PATH support should be used and how, etc).

  • Monday, June 08th, 2009, the first OpenSIPS Webinar takes place. The OpenSIPS Webinars are free webinars that aim to help people to understand and work with OpenSIPS. Topic is "Introduction in OpenSIPS".

  • Friday, April 24th, 2009, The OpenSIPS v1.5 Bootcamp training course has announced the new format (updated to synchronize with OpenSIPS 1.5), along with the 2009 schedule. The official website provides detailed information about the new training schema, the course content, dates and registration contact.

  • Friday, February 06th, 2009, OpenSIPS/OpenSER will be present at UK NOF 12 edition in Bristol, UK, on 13th of February. The topic is how current network operators can use and benefit of VoIP services built on top of OpenSIPS/OpenSER - is an Open Source platform attractive and robust enough for their demands?

  • Thursday, February 05th, 2009, OpenSIPS 1.5.0 gets a 25 % boost in DB operation by the prepared statements implementation. Following the measurement with the new prepared statements a 25 % increase in performance. See the entire set of test as well as the result interpretation
