Abstract

Voice over IP (VoIP) has the potential of significant cost savings (e.g., lower toll charges and reduced capital costs) and increased functionality. If you already have a good phone system, any change must result in reduced cost and the quality of the new system must be accepted. If you convert your phone to VoIP, it might become the most important business application running across your network. If you expect to run long- distance phone calls over your network, you should determine ahead of time if your network will provide good voice quality for the remote locations. This paper discusses the methodology that NetPredict uses for such analysis. The focus is on one of the most difficult problems in VoIP applications; effect of network congestion. The users of the capabilities discussed in this paper are enterprises, consultants and system integrators involved in assessment of network performance in support of VoIP implementation.
