Telecommunications arrangement and method for transmitting speech signals

The invention discloses a telecommunications system for transmitting voice signals. The telecommunication system encompasses a radio communications network (FKN) for switching of voice signals between mobile stations, wherein the radio communication network comprises a first means (VED1) for processing speech signals with regard to their quality. Further, the telecommunications system comprising a first (MS1) and a second (MS2) mobile station, which are designed to transmit voice signals over the radio communication network to one another, further comprising at least one of the two mobile stations second means (edge ​​detector VED2) for processing speech signals with regard to having their quality. To avoid duplicating the processing of speech signals with regard to their quality, which would lead to a deterioration of the quality of the speech signals, comprising one of the mobile stations having the second means for processing speech signals further includes a first control unit (ST1), which is adapted a first control signal to be sent to the radio communication network (STS1) so that the first device (VED1) deactivated for processing voice signals.
