QoS for Voice Traffic refers to Quality of Service mechanisms used to prioritize and optimize voice communication over a network. It ensures clear, real-time audio delivery by reducing latency, jitter, and packet loss. Voice traffic is highly sensitive to delays, so QoS assigns it higher priority compared to other types of data. Techniques such as traffic classification, DSCP marking, low-latency queuing, and bandwidth reservation are commonly used. These configurations help maintain consistent call quality in VoIP and unified communication systems. QoS for Voice Traffic is essential in enterprise networks to ensure reliable and uninterrupted voice communication.
