Abstract:
1. A method for assessing VoIP packet generation and transmission between a pair of end-points (A, B), the method comprising the steps of: a) end-point transmission of a VoIP packet sequence (TXA, TXB) and end-point reception of a VoIP packet sequence (RXA, RXB) sent between the end-points (A, B) over an IP network link; b) end-point determination of a VoIP reception signal quality (QRXA, QRXB) of the received VoIP packet sequence (RXA, RXB) and end-point determination of a VoIP transmission signal quality (QTXA, QTXB) of the transmitted VoIP packet sequence (TXA, TXB), wherein each of the end points (A, B) transmits at least one of the transmission signal quality (QTXA, QTXB) and the reception signal quality (QRXA, QRXB) to the other end point, and wherein (i) each of the end points (A, B) calculates the difference between the reception signal quality (QRXA, QRXB) determined at said end point (A, B) and the transmission signal quality (QTXB, QTXA) determined at the other end point (B, A), and (ii) each of the end points (A, B) calculates the difference between the transmission signal quality (QTXA, QTXB) determined at said end point (A, B) and the reception signal quality (QRXB, QRXA) determined at the other end point (B, A); c) supply of the determined quality information (QRXA, QRXB) to a quality indication from one of the end points (A, B) to the other end point (B, A), wherein the supplied quality information includes at least one selected from the group consisting of the quality (QRXA, QRXB) of the received VoIP packet sequence (RXA, RXB), and the quality (QTXA, QTXB) of the VoIP packet sequence (TXA, TXB); and d) end-point indication of the quality information (QRXA, QRXB) by at least one of the end points (A, B).
