Top networking consultant Uyless Black has created the essential course for every communications pro who must understand or deploy Voice over IP technology. This course couples Black's best-selling Voice Over IP book with 4 hours of expert, tightly-integrated video instruction, a hands-on workbook, and a companion Web site with even more VoIP resources. Black guides you through every key concept in the book, chapter by chapter -- covering VoIP's challenges and compelling advantages, and every standard, platform, and issue associated with successful deployment. Now, you can get world-class VoIP training in your own home or office, from a world-recognized consultant -- for a small fraction of what you'd pay for a live course! Start by reviewing the key characteristics of the Internet and IP that make VoIP a challenging proposition, including packet loss and variable delay. Next, understand the role of digital signal processors (DSPs) and voice coders in VoIP. Understand how to establish paths to service providers through the local loop via ISDN, xDSL, HFC or other approaches; review modem technology for VoIP applications; and review key protocols such as RTP, RSVP, MGCP, and H.323. Learn today's best techniques for managing performance in both private and public IP networks; understand the role of VoIP gateways and gatekeepers; and discover how IP can be internetworked with SS7.
