This paper presents a non‐intrusive method of determining network performance parameters for voice packet flows within a Voice over IP, or Internet Telephony call. An advantage of the method is that it allows not only end‐to‐end performance monitoring of flows, but also makes it possible to inspect the transport parameters of a specific network or link when delay sensitive traffic transits through it. The results of a preliminary test, to check the validity of the method, are also included.
