ITU standard audio codec that is adequate for digital voice transfer in PSTN network or
through a PBX.
- G.726: ITU standard audio codec applying ADPCM (Adaptive Differential Pulse Code
Modulation) for variable bit rates of 40/32/24/16 Kbps to 64 Kbps PCM encoding.
•Bit rate: Set the bit rate to differentiate compression ratio if using G.726 codec.
•Gain: Specify the audio input amplification.
Sound quality deterioration or howling may occur if the loudness of the sound
