<p>According to a method for narrowband compatible wideband voice communication in a DECT system (40) a wideband voice signal (200; 200') is split up into a first and a second component, wherein the first component is a narrowband voice signal (202; 202') having a spectral content of about 300 Hz to about 3.4 kHz and the second component is a wideband residue signal (204; 204'). The narrowband voice signal is encoded by using a G.726 standard encoder (205) creating an encoded narrowband voice signal (206; 206') interpretable by a narrowband capable portable part, whereas the wideband residue signal is encoded by using another encoder (207). The encoded narrowband voice signal (206; 206') and the encoded wideband residue signal (208; 208') are then transmitted to a wideband capable part.</p> |
