In this paper, we report some lessons learnt when deploying VoIP onto a small enterprise network. While these lessons resulted from a small network environment, some of the issues could have a more general applicability. Some theoretical analyses were first conducted, followed by some experimental work. An experiment was conducted for about 24 hours in order to capture the network measurement of a small LAN. The results obtained from the measurement were used in analyzing the whole network based on queuing theory. This provides ground for making judicious modifications to the network in order to support the deployment of VoIP. The modified LAN was simulated using OPNET for a period of 3 minutes after which the router began to drop some packets. With this, the simulation was terminated and results of the simulation were collected. The results obtained from queuing analysis agree with those obtained at the end of the simulation.
