SIP (Session Initiation Protocol) has become the dominant protocol for IP communications. This tutorial explains what SIP is, how it works, what the major issues for SIP deployments are, and how SIP will evolve in the future. The session focuses on the technical aspects of SIP and how it is used. It analyzes in detail the major components of SIP architecture, SIP addressing and registration, session establishment, SIP message routing and connecting SIP across the PSTN. You will learn about SIP extensions and how SIMPLE works for IM/presence. The tutorial also examines some of the challenges SIP faces, including NAT traversal (and the tools developed to cope with it: STUN, TURN and ICE) and security. The tutorial concludes with an assessment of how SIP may evolve and its role in peer-to-peer environments. You will receive an inventory of SIP resources?books, papers and organizations.

As SIP moves from the Intranet to Internet, security has gone from being a nice-to-have feature to a fundamental requirement. This session focuses on communications security aspects of SIP: How do you know you're actually talking to the person you meant to call? How do you know who's called you? How do you make sure that other people aren't listening into your conversation? The IETF has developed (and is still developing) a variety of SIP and RTP-based protocol tools for providing these security services. Topics covered include: * Introduction to communications security * Security for signaling traffic - User authentication - TLS - S/MIME - SIP Identity * Security for media - SRTP - SRTP key management (MIKEY, SDESCRIPTIONS, DTLS-SRTP, ZRTP) * Privacy and anonymity The current state of the work at the IETF and other standards bodies is covered, as is the state of SIP Security implementations across the industry. Solutions for simultaneously providing identity and knowing who is calling, dealing with spam allowing anonymous calls and providing appropriate wiretap access are described. The instructors will not only describe the various protocol components but explain how they work together as an integrated system that provides security for both signaling and media traffic. This session assumes some familiarity with SIP but no familiarity with cryptography or communications security.

While Peer-to-Peer (P2P) technology has been widely used in a wide variety of applications -- everything from file sharing to downloading game patches and Skype to distributing media content, only recently has there been an effort to take a standards-based approach to P2P. With the emergence of the P2PSIP standards work, a number of new uses for P2P have emerged, and a consensus around how P2P will be used for communications is beginning to solidify. In this session, we'll explore what the P2PSIP standard is looking to achieve, how it works, which applications of P2PSIP are being developed, when P2PSIP will reach the desk, and how it differs from other P2P technologies. We'll also take a close at what P2PSIP will mean for the bottom line as it achieves wider deployment. KEY QUESTIONS: * What are the elements of the P2PSIP standard, and where is the standard in its development? * What types of applications will be built with P2PSIP? * How will P2PSIP find its way into VOIP/UC products from the major vendors? What other sources are likely to create P2PSIP applications? * How does the P2PSIP effort attempt to deal with P2P concerns such as security and NAT traversal?

To what extent is SIP viable -- or required -- when deploying a converged, multivendor IP communications network? To help you answer that question, Ed Mier, a leading independent expert on SIP will give you a detailed report on SIP interoperability, based on the latest annual survey of SIP-supporting vendors: How many and which features interoperate, where interoperability still falls short, and where we stand with SIP "extensions." He'll discuss his conclusions with a panel of vendor representatives and the audience. KEY QUESTIONS * Which traditional voice features can be supported with approved SIP-standard specifications? What features can't? * To what extent do SIP elements from different vendors truly interoperate? Are the newer SIP-based systems backward-compatible with earlier products that were based on proprietary protocols? * In which areas of the network are SIP implementations most likely not to interoperate? * What sorts of features are being implemented as SIP extensions, and why? * Will SIP extensions always be with us, or will most if not all features become standardized over time?

The pieces are falling into place for widespread desktop video deployment: Upgraded LANs can support the traffic; cameras are cheap and easy to deploy; and more people are using video in their lives outside the office. At the same time, high-end telepresence systems are moving into the room conferencing market. So is it time for enterprises to start rolling out video as a part of their converged communications platforms? In this session, a leading industry analyst will report on the current state of the market and technology, describe key vendor initiatives in this area, and evaluate desktop video's prospects for moving into the enterprise mainstream. KEY QUESTIONS * What is the size of the market for desktop video systems? What about for room-based videoconferencing and high-end telepresence? * Who's selling the different types of video systems, and who's buying them? * What differentiates the vendors' and products' approaches to the markets and technologies? Which of those differentiators are most important? * How does enterprise usage of video today differ from the past ? more widespread, used for different reasons or by different types of users? * Where is the push for more video coming from ? executives, business managers or end users?
