Definitive SIP for engineers

Description

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