Abstract
A transmission process and arrangement transmit a voice message from a sender-side voice input unit () to a recipient-side voice output unit (). The input voice message (SN.E) is converted into a voice message signal (SS.E) that is transmitted via a transmission channel (Ü), and is converted back into a voice message (SN.A) and output by a recipient-side voice output unit (). The transmission channel includes a signal processing unit (), a sender-side radio unit () and a recipient-side radio unit (). An adjustment procedure is carried out including generating a test signal (T.E) which is transmitted in the transmission channel (Ü) and transmitted back to the measurement and adjustment unit () that generated the test signal. The measurement and adjustment unit evaluates a quality of the transmission channel and changes a parameter value (PW) of the signal processing unit if necessary. No radio unit adjustment is required.
