ABSTRACT:
A quality evaluation device for quality evaluation of an audio signal transmitted via an audio signal channel includes a unit for providing contacting information to a remote user, wherein the contacting information includes a contact address. A measurement server includes an interface designed to be a final point of the audio signal channel after an access with the contact address by the remote user, wherein a starting point of the audio signal channel is the remote user, and wherein the measurement server is further designed to subject the signal provided by the remote user via the audio signal channel to the quality measurement. The quality evaluation device further includes a unit for sending a quality evaluation result generated by the measurement server from the measurement server to the remote user. This allows any user able to access the measurement server, for example per internet, to evaluate and compare qualities with any terminals, any transmission channel settings, various telephone providers.
