A1 InnovationDays

:: Final Call for the International Developer Challenge A1 InnovationDays ::

Since almost 4 weeks, the international developer challenge A1 InnovationDays attracted more than 30 ideas from creative minds. The challenge is open to anyone who addresses the grand theme “Open Communication by Open Standards” and can come up with ideas for cool services built on IP-based communication (SIP & IMS).

Ideas can be posted on the platform until August 15, 2008.

All entries are open for voting and discussing by all users. On August 15, the 10 highest ranked ideas will be short-listed and judged by a panel of recognized experts as well as representatives from the sponsors. End of August, the best teams behind the ideas will be invited to a prototyping event near Vienna in order to realize their ideas and demonstrate their potential. The winning team can choose among several awards, such as a week of powder snow skiing in Austria. After that, the sponsor (mobikom Austria) is keen to bring your idea to the market.

All submissions must be based on Open Source Software.

Here is the announcement of project rename:

"OpenSER project and the community around it have grown considerably in the past three years. Because of its extensive development and high adoption rate, conflicting interests related to the OpenSER name and similar trademarks emerged.

Consequently, we have been forced to find a new name for the project that stands on itself and represent the project in its future expression.

Starting with version 1.4, OpenSER is called Kamailio. Existing OpenSER users can keep on enjoying the benefits of the best open source SIP server available on the market under this new name.

All project infrastructure like the website and mailing list will be in the future accessible under the domain, but we will keep the old one functional for a transition period to make the switch as easy as possible for you.

Kamailio is a hawaiian word. Kama'ilio means talk, to converse. It was chosen for its special flavour. It is hopefully easy to remember and the meaning fits well with the project purpose. We hope you like it too!"

RTP Proxy in Erlang

Just found this project:

erlrtpproxy seems to be a RTP relay for OPENSER written in Erlang, an alternative to RTPProxy and Meidia Proxy. I didn't dig for more details, but I guess it is working together with the nathelper module in OPENSER.

Hope that Erlang fans will enjoy it.

eLearning channel for Kamailio (OpenSER) config file

ASIPTO, the company I am working for, launched two months and a half ago the eLearning channel for Kamailio (OpenSER) configuration file. Since then a broad number of topics were approached:

  • introduction of configuration file structure
  • overview of SIP message execution flow
  • complete walk-through default configuration file
  • debug options
  • main routing blocks elements
  • all about assignment operations, tips and tricks
  • configuration file flags: per transaction, branch and script
  • r-uri management – best options and available alternatives to handle the request URI
  • config file statements: if, switch and while

Each document includes many examples to make easier the understanding of concepts and real word usage. With a rate of introducing couple documents and topics per week, the knowledge base of the channel is growing rapidly.

The eLearning channel offers full range of collaborative tools: forum, wiki, chat rooms, document uploading, allowing open discussions and easy interaction within the groups.

You can register now for Kamailio (OpenSER) configuration file eLearning channel here.
