G.723.1 —Describes a compression technique that you can use to compress speech or other audio signal components of multimedia service at a low bit rate, as part of the overall H.324 family of standards. Two bit rates are associated with this coder: 5.3 and 6.3 Kbps. The higher bit rate is based on MP-MLQ technology and provides greater quality.

Audio compression in Voice over IP. Telephony via Voice over IP (VoIP) and cloud phone systems also use audio compression processes. The voice quality of these compresses can be defined via MOS (Mean Opinion Score). The higher the MOS, the better the perceived voice quality. The indicator for the minimum bandwidth required for a phone call to ...

This utilizes a logarithmic compression and squeezes 16-bit samples to 8-bits. So, the compression ratio it achieves is 1:2. It’s bitrate for one direction is 64kbit/s, consuming 128kbit/s, which is a lot in comparison to other codecs. This can be freely used for VoIP applications, there aren’t any licensing fees.
