Kamailio World 2015 – The Workshops

It is now about one month and a half till the start of Kamailio World Conference 2015. Continuing with the same event structure like in 2014, the afternoon of the first day, the 27th of May, is filled with several technical workshops. These sessions are intended to give a more hands-on perspective on the subjects, with deeper technical content.


Last year, Sipwise showed how to deploy sip:provide CE – the open source out of the box IP Telephony Operator Platform – in a matter of minutes and customize it to fit better your needs. This year, Daniel Grotti, a long time SIP and Kamailio fellow, is going to show how to enable WebRTC for sip:provider CE in order to bridge the communication between the web world and the classic SIP phones. Few other typical use cases will be approached during the session.

Carsten Bock, from NG Voice, is returning with another tutorial to show more of what can be done with Kamailio for IMS and VoLTE deployments. Besides the tutorial, the plan is to have a VoLTE testbed on site for the duration of the entire event, so the participants can test with their own devices.

After presenting at the past editions the concept and the development of CGRateS, a carrier grade open source CDR rating engine, Dan Bogos is now coming with a hands-on session about how to integrate it with Kamailio for prepaid and postpaid billing.

Ability to troubleshoot SIP routing and analyze the flows on the wire is one of the core elements required for VoIP engineers. Lorenzo Mangani, one of the co-founders of Homer SIP Capture project, is going to deliver a session on how to use existing open source tools (including Homer and sipgrep, but not limited to) to make the SIP troubleshooting process easier.

Click-to-dial has been the most notoriously referred example to demonstrate and integration of web-services with telephony and became a “hello world” example application. Nevertheless numerous methods have failed to gain adoption due to various integration difficulties. CTI APIs was forgotten before it started because of too many vendor ties, B2BUA-based call-control didn’t gain traction because the simple feature wasn’t worth the trouble, and REFER-based CTD was not even understood by many vendors. With WebRTC the situation is different: the integration falls aside, as web client speaks its own language with server. With current infrastructure technologies available out there, elasticity is the key factor that balances between costs and short time scalability demands, defining the profitability. It is time to show how to build a Javascript-based client backed by openstack-powered infrastructure in a simple step-by-step manner, which can be used as getting started reference for building more complex services.

All together are providing an amazing amount of knowledge from the people with first hand experience, those that built the systems. It is a unique opportunity at Kamailio World to get face to face to interact with such people.

The content of conference days is filled with other very interesting sessions, including as well valuable technical details, presenting scalable and secure architectures or other products that can be used to complete the VoIP platforms with new features. Right now you can see details for a sections of presentations in the Schedule page.
