Communication through voice call leads to significant growth in technology in
distant areas where two or more people from opposite ends of world will
connect. This research describes a case study of voice call transfer
service. This research aims at designing a system that will allow Android
users to communicate over Wi-Fi. This design is able to transfer voice of
incoming telephone caller over Wi-Fi network at real time through UDP. It
uses client/server architecture: Server for receiving telephone call and
transferring voice (one user) and client for receiving incoming caller voice
and enables communication with server. Architecture designed could be used
on Android smart phones with telephony enabled and tablets with telephony
not enabled. Outcome of this research will allow users to communicate on
real time at no cost. Proposed design gives cost effective, reliable and
real time voice communication over Wi-Fi. It provides good and comfort
experience to users in emergency situation where user cannot effort cost for
telephone call. Proposed design is useful for educational organizations,
construction buildings, shopping malls and hospitals which point to new
possibilities for voice communication.
