Abstract
In this modern technology era, wireless technology is one of the most widely used technologies which support communication from one place to another without any physical wired connection. The purpose of this project is to design and implement a free intercom system that uses WIFI in p2p (Peer-to-Peer) or WLAN (Wireless Local Area Network) as a means of communication between mobile phones, computers (softphones), and IP phones at no cost. The switching method used is packet switching. The system will allow users to make voice, Video, and text message conversation using internet protocol, the packet will be sent from source to destination using the Asterisk-based server and WIFI based clients. As the communication is real-time the session initiation protocol (SIP) is used and some parameters such as packet sending and receiving, jitter and bandwidth utilization will be monitored using the server. The design provides a solution that eliminates the use of expensive hard-wired intercoms and Private Automatic Branch Exchange (PABX) by making use of Asterisk and WIFI.
