primary objective of this project is to design and implement a VoIP system using a Panasonic
IP gateway card.

For RapidSIP Nigeria Limited; this
service will drastically reduce their cost of running long distance calls, local calls, improve
workflow, and assigning (PIN), to a user for preventing an unauthorized user from access the
central office line. The uses of this service will be considered to be free, for the fact that
company does not have to pay for a call within branches. All offices calls will be routed
through a network; firm only needs to pay for internet service provider for bandwidth then
VoIP is considering to be free.
