| Abstract: | As the modern telephone networks begun to take shape, private companies saw a greater reliance on telephone communication. Many decide to implement their own service. So that they could handle calls internal to the organisation. Voice telephony over mobile is currently supported at a cost using service provider such as GSM, or using IP service provider at cheaper cost. The purpose of this research is to design and implement a telephony program that uses WIFI in p2p (Peer-to- Peer) or WLAN (Wireless Local Area Network) as a means of communication between mobile phones at no cost. The asterisk software will use a correlation between current address books available in mobile phones to convert phone numbers into IP addresses. The system will allow user to make voice conversation. The current system will only allow for one call per connection, and no call waiting, or conference calls. Different security services relevant for VoIP are presented and we argue that end-to- end authentication and encryption should be provided by default. |
