Abstract

The invention relates to a method and a device for converting voice data transmitted in a first voice codec mode into voice data transmitted in a second voice codec mode within an exchange centre of a communication network based on the UMTS-standard or GERAN-standard. Linear pulse code modulated voice data is guided to an input of the coding device (6a, 6b) by bypassing a time-division-multiplexing-coupling field and by compressing and decompressing devices for compressing or decompressing the linear pulse code modulated voice data.
