Răzvan Crainea's Session

This talk shows the way VoIP (voice-over IP) works as a parallel to the conventional PSTN and the different tasks OpenSIPS can take over to improve the real-time communication experience.

This talk is going to contain a brief presentation of the VoIP world: a classification of different components involved along with their purpose. Next, I am going to talk about the OpenSIPS SIP proxy/server and the different roles it can handle at the core of any VoIP platform, assisted by with various common use-cases examples.
