Offering wideband voice is a great way to ensure the best possible quality of experience for users of VoIP equipment such as IP phones. IP phone and VoIP system designers may wish to choose from the following classes of codecs, depending on the most important system-design constraints:
* G.711, G.726: Offers narrow-band voice with low processing requirements, and with typical bit-rates of 32-64 kbps. * Other narrow-band codecs with compression, such as G.729AB and G.723.1, offer bit-rates as low as 5.3 kbps, but require higher DSP processing horsepower.
* G.722: Offers wideband voice with low DSP processing requirement similar to standard G.726 ADPCM. However, it requires a bit-rate of 48-64 kbps per channel. * G.722.2: Offers wideband voice and compresses the bandwidth down to 12.65 kbps per channel. The trade-off is that it requires more processing cycles than G.722.
