METHOD OF DETERMINING THE QUALITY OF VOICE DATA WITH TRANSMISSION VIA A NETWORK, METHOD OF AND AN APPARATUS FOR PERFORMING A TELEPHONE CALL

摘要

A method of determining the quality of transmitted voice data can include:providing voice data at a transmitter side in a first data format,providing a first test signal in the first data format,combining the voice data and the test signal to form input data,transmitting the input data in a transmittal data format,receiving the transmitted input data at a receiver side to obtain output data,removing at least portions of a data packet in the output data or of a data packet derived therefrom in order to derive a second test signal, andanalysing the derived second test signal by applying a predetermined analysis criterion in order to obtain at least one value for a quality indicator. An apparatus and system can also be configured to utilize embodiments of the method.
