Research and Markets (http://www.researchandmarkets.com/reports/c39043) has announced the addition of "E-Learning Course: Voice over IP" to their offering.

"Voice over IP" provides an introduction to the principles and operation of telephony services that operate over Internet Protocol (IP) networks and includes detailed treatment of SIP and H.323. It is suggested that this course is studied with TRG "Advanced IP networks".

Introduction: The provision of telephony over the same types of network that carry Internet traffic is an increasingly important subject for the telecommunications industry. So-called Voice over IP (VoIP) services are likely to become as prevalent as conventional PSTN services.

This course aims to provide an introduction to the principles and operation of telephony services that operate over Internet Protocol (IP) networks.

Pre-requisites: Understanding of issues relating to the provision of a public telephone service including numbering, role of signalling and Grade of Service calculations. It is recommended that MediaNet course A: "Voice Switching" is studied before attempting this course. Also: understanding of the principles of operation of networks using IP. The e-learning course TransNet course F: "IP Networks" covers this topic. Although not a pre-requisite, the study of TransNet course G: "Advanced IP Networks" would also aid the understanding of the transmission aspects of a VoIP service.

"Voice over IP" forms part of the MediaNet suite of courses.

MediaNet is a suite of interactive, multimedia e-learning courses designed to run under Windows(TM) 2000 Professional or XP.It provides training in the technical aspects of delivering voice and video services and consists of three separate but integrated courses:

A Voice switching

B Voice over IP

C C7 signalling

Each MediaNet course provides several hours of in-depth, authoritative technical training.It also employs interactive simulations, hypertext links and question sessions to fully involve the trainee in the learning experience.

This course provides personalised training with each trainee able to make his/her on notes and place bookmarks. A record of progress and level of achievement is recorded for each trainee.

It also provides a structured assessed course and can also be used to browse for revision or reference.

The course can be studied in isolation or as an integrated suite; each chapter of a course includes revision links to relevant subjects covered in the other MediaNet courses.

Target audience:

MediaNet is designed for those studying for a career in telecommunications and who require a detailed knowledge of telephony and video systems.

It is also aimed at technical staff involved in the operation, installation or maintenance of systems that deliver telephony and/or video-based services.

Course Content Contains:

-- VoIP packet transport: review of the advantages of a Voice over IP (VoIP) telephony service over that provided over a circuit-switched network

-- Voice encoding and bandwidth: processing of speech including PCM encoding, echo cancellation, compression and silence suppression

-- Session Initiation Protocol (SIP): role of the functional components of a VoIP system using SIP including user agent, proxy server, location and redirect servers

-- H.323 VoIP systems: role of the various protocols involved in providing an H.323 audiovisual service inc. H.225, H.245, and the Real-time Protocol (RTP)
