Codecs

Codec — a program or algorithm designed for encoding and decoding multimedia data (for example, audio and video streams). In IP telephony, codecs are used to compress and transmit voice information in digital format through a network connection.

KOMPaaS codecs in use:

• Client — 729, 711a (alaw).
• Operator — 711a (alaw).

G.729 and G.711a codecs are standards in IP telephony for compressing and transmitting voice information over network connections.

G.729 — a lossy compression codec that transmits voice at a lower data rate compared to G.711. This significantly reduces network load, which is especially useful with limited bandwidth. G.729 is often used in environments with limited network resources.

G.711a — an uncompressed codec that provides the highest sound quality for voice transmission. However, it requires a higher data transfer rate, which can affect network load. G.711a is used where excellent sound quality is critical, such as in corporate or high-quality VoIP systems.

Both codecs are widely used in IP telephony. G.729 is preferred with limited bandwidth, while G.711a is used for lossless sound transmission.
