5.1.1 Codec
A CODEC (COmpressor/DECompressor) is an algorithm for taking voice or video and compressing the
information. This type of codec combines analog-to-digital conversion and digital-to-analog conversion
functions in a single chip. The Codec is used to compress the voice signal into data packets. Each Codec
has different bandwidth requirement. There are 9 kinds of codec, G.711/Ulaw, G.711/Alaw, G.729, G.723,
G.726(16K bps), G.726(24K bps), G.726(32K bps), G.726(40K bps), and iLBC.
