When the Penguin Rings 

When the Penguin Rings

Jan Vanhercke (C-CURE)

Voice over IP is an upcoming technology that is generally perceived as expensive and immature. Nevertheless solutions on the Linux platform exist and can be used today as a replacement for a traditional telephone switch.

This talk will discuss many aspects of IP telephony, including:

overview of the standards (H323, SIP)

integration with ISDN

architectures and functions

how to roll your own

The talk will be split in two parts. A more generalistic overview of the different components and concepts, and a more practical part on the Linux implementation.
