Voice codec support determines the quality and bandwidth efficiency of voice calls. The best codecs are those that provide high audio quality while optimizing bandwidth usage, such as G.711 for high-quality audio and G.729 for low bandwidth. Different models may support various codecs to suit different network conditions. The Snom 3CX D865 and D862 both feature HD audio with advanced noise reduction, indicating support for high-quality codecs. With multiple codec options available, you can select a phone that delivers optimal audio performance for your specific environment.
