Ars Technica launches article series introducing the SIP protocol

Jan.25, 2010 in

Over at Ars Technica, author Gilad Shaham has started a series of posts about the SIP protocol. So far the two installments are:

Wired for sound: how SIP won the VoIP protocol wars
VoIP in-depth: An introduction to the SIP protocol, Part 1

The first article gives some background about SIP and goes on to explain how SIP prevailed over H.323 as the dominant standard for VoIP traffic today. The second article goes through the details of basic SIP messaging and explains how SIP proxy servers and registrars fit into the picture, complete with some diagrams that nicely explain call flows. The author indicates that the next article in the series will dive into SIP calls in more detail.

If you are new to VoIP or to the SIP protocol, both of these articles are great tutorials that will help you learn more about what SIP is all about. If you are familiar with SIP, you still may find some interesting tidbits mixed into the text. The articles are good to see and I’m looking forward to reading the next installments!
