GOAL Class room Design Establishing class room atmosphere Interaction between Professor and Students

INTRODUCTION What is video telepresence? Virtual Presence. Has became a main tool for multinational companies. Our Professor had an idea to implement this technology for a class room.

PROJECT ROUTE MAP INSTALLATION OF ASTERISK ESTABLISHING VIDEO CALL CONFIGURE CODEC DEVICES CONFIGURE TWO SIP ACCOUNTS ON ASTERISK

CODEC : It is a device for encoding and decoding a digital data stream or signal. Supports multimedia data streams by using some audio and video commanding standards Standards that we have used G.711(µlaw) for audio H264 for video

ASTERISK It powers IP PBX systems, VoIP gateways. Free and open source. Capable of interfacing with several telecom, VoIP protocols and codecs.

MAKING of IP-PBX: Install prerequisite packages libncurses-dev libsdl1.2-dev libsdl-image1.2-dev libavcodec-dev libswcale-dev Build and install an asterisk with all the above.

CONFIGURATION OF SIP In Asterisk In codec Two sip account are created in the above softwares with 1234 and 1235 as two accounts Dial up plan

FUNCTIONING OF BLOCK DIAGRAM

APPLICATIONS Students who are on distant learning courses. Guest lectures by prominent Professors from remote location. Even in the field of medical.

WHAT WE LEARNT SIP signaling. Codecs which support multimedia streams. Asterisk software. Linux commands

CONCLUSION Thus we are able to establish AN AUDIO over IP through the codecs.
