Abstract
The invention concerns a process for transmitting coded voice signals in at least one telecommunication network, according to which the voice signals are transmitted via channels with low data rates with a data-reducing code and via channels with higher data rates also with the data-reducing code. Furthermore, inband-signalling, which identifies the data-reducing code and is used to switch encoders and decoders, is transmitted via the channels with higher data rates.
