ABSTRACT
Today, Internet is becoming increasingly popular in usage. It is used not
only for text based data communication only, but also for multimedia
communication, for example, audio, video and graphics. This seminar deals with
the audio communication over Internet : Voice Over IP. VoIP is the ability to make
telephone calls and send faxes over IP-based data networks with a suitable quality
of service (QoS) and superior cost/benefit . Everyone is talking about VoIP and
everyone wants a piece of the pie.
Voice Over IP (VoIP) enables user to make calls in real time between
any combination of phones and PCs. VoIP converts voice traffic into data packets
and transports them over the Internet. This report first discusses the basic of VoIP
including its motivations and working. Then it focuses on Quality of Services in
VoIP. The protocols and standards that exist today are also examined. Finally the
key problems of present VoIP technology are discussed followed by its expected
future.
Voice Over IP is growing daily and catching on with thousands of
business as well as PC users who have long on this developing technology and its
applications.

INTRODUCTION
Voice over IP is mainly concerned with the realization of telephone
service over IP-based networks such as the Internet and Intranet. IP telephony is
currently breaking through to become one of the most important service on the net.
The actual breakthrough was made possible by the high bandwidth available in an
intranet and, increasingly, on the internet. Another fundamental reason is the cost
associated with the various implementations.
The public telephone network and the equipment makes it possible are
taken for granted in most parts of the world. Availability of a telephone and access
to low-cost, high quality worldwide network is considered to be essential in
modern society (telephone are even expected to work when the power off).There is,
however, a paradigm shift beginning to occur since more and more communication
is in digital form and transported via packet networks such as IP, ATM cells, and
Frame Relay frames. Since data traffic, there has been considerable interest in
transporting voice over data networks.
Support for voice communications using the Internet Protocol(IP), which
is usually just called “Voice over IP” or VOIP, has become especially attractive
given the low-cost, flat-rate pricing of the public Internet. In fact, toll quality
telephony over IP has now become one of the key steps leading to the convergence
of the voice, video, and data communications industries. The feasibility of carrying
voice and signaling message over the internet has already been demonstrated but
delivering high-quality commercial products, establishing public services, and
convincing users to buy into the vision are just
beginning.
