Wikipedia / G.723

G.723 is an ITU-T standard speech codec using extensions of G.721 providing voice quality covering 300Hz to 3400Hz using Adaptive Differential Pulse Code Modulation (ADPCM) to 24 and 40kbit/s for digital circuit multiplication equipment (DCME) applications. The standard G.723 is obsolete and has been superseded by G.726.
