VoIP class at Vigo University

My colleague Antón (@AntonRoman) and myself visited last Monday the Telecommunication Engineering School at Vigo University in order to give a talk about VoIP, technologies and project that we’re involved in Quobis. As the year before, we were invited by the professor of the subject Switching laboratory”., Martín López Nores, to prepare a Kamailio practical exercise.

Antón started explaining some basic VoIP concepts and then he went through more advanced ones mainly focused in Kamailio SIP server (slides).Then, I made a review and a demo of the most common VoIP vector attacks that we found every day “in the wild” and their available countermeasures (slides).

As the last course, we extended the mandatory practice with an optional exercise (you can download them from the links below):

We encourage the students to give it a try, I strongly think this practice could be very useful for their professional future. In fact,  Andrés Souto (@kai670), who did a great job last year while being a student of the last course, is working now with us at Quobis. And last, but not least, we would like to thank Martín for this opportunity of sharing a good time and discovering skilled students.
