Abstract
A system for assessing a voice communication quality of a communication path between first and second nodes over a network, wherein coded data of voice communication signals are transferred in a stream of packets via the communication path, including: a capturing unit for capturing at the first node at least one packet containing coded data representing non voice signals among the packets of the coded data to be transferred from the first node to the second node; a replacing unit for replacing a part of the coded data representing non voice signals in the captured packet with a predetermined code before the captured packet is transferred from the first node; a retrieval unit for retrieving at the second node said at least one packet containing coded data representing non voice signals; and an assessment unit for assessing the voice communication quality of the communication path.
