Kamailio (OpenSER) Presence Server: Dialog Info Support

Developed by Klaus Darilion and sponsored by Silver Server (www.sil.at), Kamailio (OpenSER) introduced support for Dialog Info presence states - RFC4235 - INVITE-Initiated Dialog Event Package.

There are two new modules introduced:

* pua_dialoginfo: gets dialog states from dialog module and sends PUBLISH with the dialog state in RFC 4235 conform XML documents
* presence_dialoginfo: extends presence module to handle PUBLISH with dialog-info. Allows aggregation of multiple XML documents into one document.

With these modules you can have BLF without the need for an PBX (Asterisk). It is know to work with SNOM and Linksys phones. Linksys requires some tweaking with module parameters.

For more see the readme files:

A1 InnovationDays Remarks

Returning from about two weeks of journey, I am catching up with work now. However, it worth to mention here some events I attended during past weeks.

The A1 InnovationDays Sprint was really challenging.
http://www.a1innovations.at/en/static/a1innovationdays

While participating to other coding sessions in the past, this one had the premises to make it great:

- nice location, one hour drive from Vienna, Austria, at Monastery Und in Krems. An old site turned into a convention place

- competition - five teams ran head to head to win. Finally the project "Spontaneous live comment as A1 sports reporter" got the prize, but I could say all the projects have big potential and the results after two days of coding were impressive: "Thunderbird plug-in for Unified Communications", "SIP Website Widget", "Automated Audio/Video Greeting Service" and "SIP extension for Disko framework". I will try to detail each one in separate posts

- vast knowledge base - it would be hard to get again in same room technical people from various domains working together: Web 2.0, graphic design, SIP, voice and video processing, embedded systems, GUI, GSM/Mobile technology, IMS

The only barrier seemed to be the weather, very nice, warm and sunny, trying to attract out attention away from coding.

However, the most important aspect of the event was the implication of the A1 - Mobilkom Austria in such event. It is the first mobile operator I have seen encouraging Open Source initiatives. Worth congratulations and let's hope they will be followed by other similar companies.

Kamailio updates

Some updates concerning two main topics discussed on the mailing lists. First, the project name, many expressed the concern that a rename in short time will create more confusion. As we are not in front of a new major release, I think it is better to postpone this process for a while and focus on the second topic, the organization for the project.

For this one, I have to thank personally to many people from the list that wrote us, giving suggestions and helping finding solutions. As a result, we are working to create the draft of statute for organization, but we are also investigating the option to join an existing
organization, dedicated to hosting of open source projects.

Meanwhile, the svn repository got couple of new features as well as refactoring of some modules. 1.4.1 will be released soon as we got a bunch of important fixes in the 1.4 branch. Most probably another release in 1.3 branch will follow.

I am more proud of this success as I am coming from same place, Turburea, Gorj County, South-West Romania. The area seems to have precious resources for long distance running athletics. Constantina’s colleague, Lidia Simon, who won silver medal of marathon at Sidney Olympic games 2000, comes from same village.

Congratulations!
