Cisco CloudCenter: Get the Hybrid IT Advantage


Definition - What does G.722 mean?

G.722 is an ITU Telecommunication Standardization Sector (ITU-T) standard approved in 1988. It operates at 48, 56 and 64 Kbps using a codec technology based on a sub-band of adaptive differential pulse code modulation (ADPCM). The G.722 samples audio data at a rate of 16 KHz, twice the speed of traditional telephony interfaces. This results in superior clarity and audio quality.

Other ITU-T wideband codec include G.722.1 and G.722.2. They use different patented compression technologies.

Techopedia explains G.722

G.722 describes the characteristic of the wideband audio coding system, which is used for a variety of high-quality speech applications, including high-quality Voice over Internet Protocol (VoIP). The entire coding system uses sub-band adaptive differential pulse code modulation with bit rates of 64 Kbps and is referred to as 64 Kbps audio coding.

G.722 is mainly used in VoIP such as on local area networks, where network bandwidth is easily available and offers improvement in speech quality over narrow-band codec such as G.711, without an increase in implementation complexity. G.722 is also used by broadcasters for sending commentary-grade audio over single 64 Kbps integrated services digital network B channels.

G.722 VoIP is carried in Real-Time Transport Protocol payload types.
