Abstract:
1. A method of VoIP load management to assure voice quality in a packet switched network, comprising: determining a number of VoIP calls currently active in the packet switched network; determining the maximum number of VoIP calls the packet switched network can facilitate without the loss of voice quality; allowing the admission of a new VoIP call when the addition of the new VoIP call would not exceed the maximum number of VoIP calls; and blocking the admission of a new VoIP call when the addition of the new VoIP call would exceed the maximum number of VoIP calls; and wherein determining the maximum number of VoIP calls the packet switched network can facilitate without the loss of voice quality comprises determining bandwidth for a plurality of communication links between a plurality of gateway pools, determining the number of frames per IP packet used to transmit data in the packet switched network, and generating a capacity table indicating the maximum number of VoIp calls permitted to the plurality of communication links based on the bandwidth of each communication link and the frames per IP packet.
