ABSTRACT

I will talk about voice services in packet-switched (VoIP) and circuit-switched (traditional telephony) networks, using Linux and commodity hardware. This will include short introduction into telephony in general, VoIP and PSTN type of telephony, plus overview of VoIP services (and popular opensource software packages used to implement those services) and kernel interfaces that used in that packages. I will cover the topic of connection to the Public Switched Telephony Network using digital interfaces (E1/T1), kernel support for it in framework called "zaptel", and userspace integration issues. The conclusion is about current trends in Linux-based and open-source telephony.

This is a second run of my presentation which I gave on the Ottawa Linux Symposium’2007.
