Understanding VoIP Codecs and How They Affect Call Quality

VoIP allows businesses to communicate with customers near and far with reliable voice quality through the Internet.

A VoIP codec controls audio quality of VoIP calls, bandwidth usage, and data compression.

A codec converts and compresses your voice into digital data packets so it can travel over the internet. When the data packets reach their destination, the codecs decompress and convert them back into clear voice signals, ensuring that your voice sounds crisp and smooth to the receiver.

Codecs play a vital role in determining the quality of your VoIP calls. They influence how smooth your calls are, ensuring minimal audio delays, clarity of audio, and better call quality.

G.711, G.722, G.726, and G. 729 are some of the commonly used codecs. G.711 and G.729 are extremely popular.

At United World Telecom, we support the G.711 codec, including both μ-law and A-law variants. Our call quality boasts an average MOS of 4.3, ensuring crystal-clear communication.
