The purpose of our project is to travel the voice over the data network using
IP Telephone technology. For this purpose we are using call processing
server known as the Cisco Callmanager in which all the services are running
which we need to accomplish our requirements. The Cisco Callmanager
transfers voice packets across the data network. If a person wants to talk
with another person whether within office, outside office or whether in a city
or outside the city but should be in the same network. He is now able to
make a call using his own network without any cost. With this project we are
basically bypassing the PSTN network.
