Name	Type	Description
VoIPSender	simple module	This module 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.
