Abstract

The present invention relates to a method and an arrangement and an apparatus for transferring sound in a digitized form. The sound is received by a microphone means (18) of a handset means (10), whereafter it is converted in said handset means (10) from an analog form into a digitized form. The digitized signal is transferred through an operational connection (19, 22, 23) to a data processing device (20), from which it is further transferred through an operational connection to a communications network (8). The data processing device (20) operationally connected to the communications network (8) can correspondingly receive a digitized sound signal from the network. Said digitized signal is transferred through an operational connection (19, 22, 23) to the handset means (10) and is thereafter converted in said handset means into a sound signal to be represented by means of a speaker means (18).
