Abstract

A Hybrid of Traditional Telephony and Internet
Telephony is a communications network that
integrates the traditional Public Switched
Telephone, Network (PSTN) and the Internet
Protocol (IP) based packet switched network. In
this work various types of hybrid PSTN-IP
telephony connections including the currently
available service are explored. Selected hardware
and software tools have been used to develop a
hybrid Internet telephony service in LAN The
Microsoft product TAPI 3.0 is used to develop all
the interfaces and the ITU-T H.323 standard is
used as the voice over IP. The software developed
for this work has been tested and found working
satisfactorily. The problem associated with full
duplex on line communication is also addressed.
This system has been implemented successfully.
