G.711 Log-PCM encodes voice frequency signals yield rate 64Kbits/s 8000Hz sampling rate. G.726 Adaptive Differential Pulse Code Modulation (ADPCM) Speech Codec converts 64Kbits/s ALaw Mu-Law Pulse Code Modulation (PCM) channel from 16Kbits/s channel. G.723.1A Dual Rate Speech Coder provides coded representation used compressing speech either 6.3Kbits/s, producing higher quality reproduction, 5.3Kbits/s, providing additional flexibility. Includes Amex which implements silence compression techniques reduce transmitted rate during silent interval speech. G.729AB-The G.729 Recommendation describes algorithm speech coding 8kbps. G.729A less-complicated version G.729 vocoder, while G.729B used reduce transmission rate during silent periods speech. G.168 Line Echo Canceller voice-operated device which reduces echo subtracting echo estimate from circuit echo. DTMF Detection DTMF Generation-The DTMF signal, also known Touch Tone signal, comprised frequencies which represent single digit telephone keypad. DTMF signaling used call control such features call forwarding, conference calling, etc. Voice Activity Detection (VAD) detects voice activity activates deactivates transmission packets optimize bandwidth. Comfort Noise Generation (CNG) generates background noise during silence frames phone calls. Call Progress Tones (CPT) tones used indicate current status call.
