  • Method, system and signal generator for quality determination of an IP network connection
    Patent number: 9130767
    Abstract: The present invention relates to a method, a system and a VoIP signal generator for determining the quality of an IP network connection, comprising the steps of generating a measuring signal by way of a signal generator for measuring the quality of an IP network connection; determining, by way of the signal generator, for each of the generated at least one measuring signal the respective signal quality of each generated measuring signal; and simultaneously transmitting the at least one measuring signal and the respective quality information over the IP network connection to a receiver.

  • Method and apparatus for assessing VoIP packet production and packet transmission and indication at the end points involved in the VoIP communication
    Patent number: 8718044
    Abstract: The present invention relates to a method and a device for assessing and indicating the quality of VoIP calls, comprising the steps of end-point reception of the VoIP packets over an IP network link, end-point determination of the VoIP quality (QRX) of the received VoIP packet sequence, the VoIP quality (QTX) of the transmitted VoIP packet sequence, exchange of the quality information (QRX and QTX) between the end points, calulation of the difference (QRX-QTX) between the received VoIP quality and the VoIP quality transmitted by the other side; supply of the determined VoIP quality information to a quality indication; and end-point indication of the quality information in optical and/or acoustic form.

  • Method and arrangement for testing the transmission system and method for quality of a speech transmission
    Patent number: 7796530
    Abstract: Method for testing the transmission quality of a bidirectional real speech transmission or multicast connection over an IP network between a first VoIP endpoint and a second VoIP endpoint. A first number of the RTP speech packets transmitted from the first to the second VoIP endpoint, and a second number of the RTP speech packets transmitted from the second to the first VoIP endpoint being detected over a predetermined, sufficiently long time period, and the first and second numbers being subjected to arithmetic processing, as a result of which a value representing the transmission quality is obtained.
