The invention relates to a method for transcoding audio signals in a communications system. In order to improve the inter-operability between units () capable of handling wideband audio signals and units () or network components () capable of handling narrowband audio signals, it is proposed that first, an audio signal is received in a network element () of a communications network via which said audio signal is transmitted. Next, it is determined in said network element () whether a transcoding of the received audio signal is required. In case a narrowband-to-wideband transcoding of the received signal is required, the received narrowband audio signal is transcoded into a wideband audio signal in the network element (). The generated wideband audio signal is then forwarded to the receiving terminal (). The invention equally relates to a corresponding communications system and its components.

The invention is a system, a method of transmitting messages selectively as text or non-text from an entity () in a network (and), and an entity in a network. A system in accordance with the invention includes at least one terminal (); a network containing the at least one terminal; an entity in the network which provides messages selectively as text or non-text to the network in a speech encoded form; and wherein the messages are transmitted in the speech encoded form by the network to the at least one terminal which reproduces the messages to a user thereof in either a text form or by a sound reproduction device of the at least one terminal.
