Description

Codecs are used to convert an analog voice signal to digitally encoded version. Codecs vary in the sound quality, the bandwidth required, the computational requirements, etc

Per Call Bandwidth requirements for various codecs

Codec & Bit Rate (Kbps) Codec Sample Size (Bytes) Codec Sample Interval (ms) Voice Payload Size (Bytes) Voice Payload Size (ms) Bandwidth Ethernet (Kbps)
G.711 (64 Kbps) 80 Bytes 10ms 160 bytes 20ms 87.2Kbps
