New Kamailio Module: Erlang

Before freezing the development for next major release – Kamailio v4.3.0 – several modules and other relevant additions were pushed in a rather short period of time to git repository. Now, we are trying to look briefly at few of them in a series of posts in order to let everyone know about them.
First to talk about it is the erlang module, contributed by Seudin Kasumovic of Bicom Systems. Erlang is a functional programming language tightly related to telecom environment, with built-in support for concurrency, distribution and fault tolerance
The module enables interaction of Kamailio with Erlang nodes, allowing to send and receive Erlang messages as well as RPC calls between each other. You can read more about it at:
Seudin will also present at Kamailio World Conference how this module can be used and its benefits for scalability and reliability.

Kamailio World 2015 – Grants for Students

Given the roots and the tight relation of Kamailio project with the academic environment, we are offering three seats at Kamailio World Conference, May 27029, 2015, in Berlin, to students enrolled in universities or research institutes (both bachelor and PhD programs qualify).
Last year we tried it locally with the universities in Berlin and this year we want to extend it, as there might be young people interested to travel a bit and attend the event.
If you are a student and want to participate, email to registration@kamailio.org . Participation to
all the content of the event (workshops, conference and social event) is free, but you will have to take care of expenses for traveling and accommodation. Write a short description about your interest in real time communications and what is the university or the research institute you are affiliate to.
Also, if you are not a student, but you are in touch with some or have access to students forums/mailing lists, it will be very appreciated if you forward these details.
More information about Kamailio World is available on the web site:
Looking forward to meeting many of you in just few weeks in Berlin!
