Definitive H.323 for engineers

Description

A hands on course covering IP telephony with H.323. The course starts with a brief review of knowledge students should already possess including RTP and RTCP. The main focus is on H.323 protocols though, progressing from what H.323 is through signalling, call processing and architectures, moving onto more advanced issues including security, multimedia, conferencing, and interoperability. Hands on practicals follow each major theory session.
