In general AMR codecs can operate at lower C/I values and allow an improved utilization of the frequency spectrum. The voice quality may not be the limiting factor anymore in AMR calls, but the performance of the signaling channels. To allow a higher utilization of the frequency spectrum 3GPP (Was it in Release7?) has adapted the idea of Repeated FAACH / SAACH. These are than also (optional) features for mobil stations.
