Why?
In the world of VoIP communications, the quality of sound and reliability of the call can vary greatly depending on the audio codec being used. A codec is responsible for converting and compressing audio for storage or transmission, and the choice of codec can significantly impact both the clarity of the conversation and the bandwidth used. Understanding the technicalities of different audio codecs is essential for anyone setting up or troubleshooting a VoIP system, especially when using services like Voys.
In this guide, we will explain how audio codecs function, why they can cause problems in VoIP calls, which codecs are optimal for VoIP communications, and what you can do to ensure your calls are clear and reliable.
For most customers, we recommend using G.711 (A-law/PCMA) as the default codec for compatibility and stability with other telecom providers.
