By TMCnet News

Norwalk, CT – July 8, 2011 – TMC and Crossfire Media today announced that the SIP Tutorial will return to ITEXPO on September 15, 2011, in the Austin Convention Center.  The full day SIP Tutorial focuses on SIP technology- from SIP messaging through server types, security, firewall and NAT operation, SIP trunking, troubleshooting and SIP in Unified Communications.

“Web based services, cloud computing and peer-to-peer present a challenge to mature SIP based VoIP technology, making it imperative to be familiar with all the current capabilities of SIP as well as the recent enhancements,” said Crossfire Media’s Carl Ford. “The SIP Tutorial helps attendees learn everything they need to know in a single day.” 

Topics covered in the SIP Tutorial include:

  • Standards in Telecom and Internet
  • Core SIP Standards                                       
  • SIP Services
  • SIP Security Overview
  • Real Time Communications on the Web
  • P2P and SIP

These sessions are hosted by two of the most prominent authorities in the SIP world: Dr. Henry Sinnreich, and Dr. Alan Johnston.

Dr. Henry Sinnreich, considered by many to be the Godfather of SIP, developed the first commercial SIP service used by a major carrier. He has authored several books on SIP, and is an active contributor to IETF SIP standards work. 

Alan Johnston is Adjunct Professor at Washington University in St. Louis, and Director of the SIP Forum. He is a co-author of the core SIP specification, and other standards. He holds several patents, and is the author of four books on SIP and VoIP security.

The SIP Tutorial is sponsored by the SIP Forum, which is an IP communications industry association that engages in numerous activities that advance and promote SIP technology, such as the development of industry recommendations, the SIPit interoperability and testing events, special interoperability workshops, and general promotion of SIP in the industry.

Registration for the SIP Tutorial remains open. All SIP Tutorial attendees in Austin will have full access to the ITEXPO Exhibition Floor, featuring hundreds of IP Communications and Broadband Internet companies, as well as all 4GWE and ITEXPO networking events. Members of the media interested in media credentials should contact Todd Keefe at For Immediate Release PR.
