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 the 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 these 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. Dr. Cullen Jennings currently serves as IETF Real Time Applications Area Director.

Many large enterprises would like to begin migrating from PRIs to IP/SIP trunks, because the potential savings could be very significant. But these services are not ubiquitously available, and interoperability issues still exist. So when will you be able to adopt SIP trunks across your enterprise, and how will the affect your services costs and operational expenses? This session will help you get answers. KEY QUESTIONS: * What is the true status of SIP trunk availability? Who are the leading providers? * How do the costs of SIP trunk services compare with PRIs? * What interoperability issues remain and what is being done to overcome them? * How will SIP trunk implementation affect other issues in your IP Telephony deployment such as security and quality of service?

Enterprise customers have heard a lot about carrier managed and hosted services, but a related trend is the emergence of Software as a Service (SaaS). How is SaaS related to more traditional concepts of network-hosted voice services, and how can SaaS be leveraged within a Unified Communications system? This session will examine the technology aspects of SaaS as they relate to voice, and will look at cost factors. KEY QUESTIONS: * How is the concept of SaaS similar to hosted VOIP services? How is it different? * What are the carriers' offerings in SaaS, and what is the possibility for integrating this with premises or network-hosted voice systems? * Can enterprises save money with a SaaS strategy incorporated into their UC strategy? * What UC applications and capabilities are candidates for a SaaS offering? How can you best integrate such offerings into your premises-based UC system?
