Starting from Release 8.0(1) , CVP Supports the use of G.722 codec . G.722 is an ITU standard codec that offers a significant improvement in speech quality over older narrowband-codec, such as G.711 without an excessive increase in implementation complexity, but with an increase in the bandwidth required.G722 enders a more natural sounding human voice than G.711, in part because it uses higher sampling rate than G.711.It is useful in fixed-network VOIP applications where ever its greater required bandwidth does not make it prohibitive.
G.722 enables bitrates of 64, 56 and 48 kbits/s; however, only the 64 kbits/s bitrate is supported.
Note:
G.722 enables bitrates of 64, 56 and 48 kbits/s; however, only the 64 kbits/s bitrate is supported.
Note:
- The Unified CVP IVR service does not support G.722. Unified CVP endpoints that connect with the VXML gateway still require support of G.711.
- There is no transcoding support between G.722 and G.711, but media server .WAV files donot need to be converted to G.722 because renegotiation takes place automatically when necessary.
