What is G.711 codec?

G.711 is a VoIP codec that delivers high-quality, uncompressed audio, typically used for enterprise communications.

G.711 is a widely used codec in VoIP systems that provides uncompressed, high-quality audio at 64 kbps per channel. It uses pulse code modulation (PCM) to convert analog voice signals into digital data. G.711 is known for maintaining excellent call quality, making it the preferred choice in enterprise environments where bandwidth is sufficient. However, because it requires more bandwidth than compressed codecs like G.729, it may not be ideal for low-bandwidth or congested networks. G.711 is commonly used in SIP trunking, PBX systems, and VoIP platforms where call quality is a top priority. Its compatibility with most VoIP equipment and protocols makes it a reliable and widely adopted codec for business communication.
