In this paper, we assess the impact of active queue management (AQM) on the quality of service of voice over IP (VoIP). Some of the most representative AQM schemes are analyzed through extensive simulations; evaluating its effect on the perceived quality of voice calls. We investigate different network scenarios, changing network loads and scheme control parameters. Network impairments are related to user perception by means of well known algorithmic models, expressing user satisfaction in the MOS scale. Our main results shows that the use of active queue management schemes significantly improve the perceived quality of voice calls, offering adequate user satisfaction.
