Supported Audio Codecs for Crazytel Services

Understanding Audio Codecs: Before we dive into the details, a quick primer: Audio codecs are essential for compressing and decompressing audio in real-time communications, like voice calls. They ensure your conversations sound clear and use bandwidth efficiently.

Crazytel Supported Codecs: For optimal performance and compatibility, Crazytel currently supports the following widely-used audio codecs:

1. G729 a/b: Known for its low bandwidth usage and decent voice quality.
2. G711: Offers high voice quality at the cost of slightly higher bandwidth consumption.
   • PCMU (G711u): The μ-law variant, commonly used in North America.
   • PCMA (G711a): The A-law variant, prevalent in international markets.
3. G722: Provides high-definition (HD) voice quality, ideal for environments where bandwidth is not a concern.

Important Note: While the above codecs are officially supported and thoroughly tested, attempting to use other codecs may still work but is not guaranteed and is done at your own risk. For the best user experience and to avoid potential call quality issues, we recommend sticking to the listed supported codecs.
