Name	Type	Description
VoIPReceiver	simple module	This module represents a model for the receiver of Voice-over-IP (VoIP) traffic. It receives packets sent by a VoIPSender application via UDP and records statistics such as packet loss, end-to-end latency, jitter, and throughput. Furthermore, it computes and emits a MOS (Mean Opinion Score) value, which represents the Quality-of-Experience of the end users.
