Abstract
Devices, softwares and methods for prioritizing between voice data packets for discard decision purposes. A perceptual importance of a voice data packet relative to the others is determined at encoding, preferably according to the content of the encoded sound. The relative importance is represented as a comparative discardability code in the packet. If a discard decision is made, it takes into account the comparative discardability code of the packet, thus preferring to discard the unimportant packets more frequently.
