The present paper addresses multiparty telephone conferences with asymmetric quality degradations. We propose a systematic method that allows to investigate how individual technical degradations can lead to the perception of quality impairments by the different interlocutors in a conference call. By conducting this analysis for a number of degradations, a detailed picture on the complexity of assessing asymmetric conditions is drawn, which in turn verifies the need for such strictly systematic assessment approaches.
