Codec Net Bandwidth per call (kbps) Used Bandwidth per call (kbps) Min. Compression Delay (ms) Usage G.711 a-law 64 96 10 Uncompressed, best voice quality, European audio-digitizing G.711 u-law 64 96 10 Uncompressed, best voice quality, American audio-digitizing G.723.1 6.3 17 30 Good voice quality at lowest bandwidth, like analog phone, acceptable delay G.729 G.729a G.729b 8 40 10 Best relationship between voice quality and used bandwidth, low delay. G.729b is the silence suppression scheme for G.729a and is supported by the SmartNode family. For the sake of simplicity SmartWare and SmartNode always use the term G.729a, implicitly meaning G.729a and G.729b.
