//
// Represents a model for the sender of Voice-over-IP (VoIP) traffic.
// It generates packets by alternating "talk spurts" and "silence" periods, with their respective
// durations modeled by a Weibull distribution. During talk spurts, fixed-size packets are
// generated periodically and sent over UDP to a specified destination address and port.
