 In addition, you can use the  [Media Stats API](../../../../concepts/voice-video-calling/media-quality-sdk.md) to monitor and track real-time network performance from the Web client.
 There are two metrics related to the audio delay: `rttInMs` and `jitterBufferDelayInMs`.
 
-The [rttInMs](../../../../concepts/voice-video-calling/media-quality-sdk.md?pivots=platform-web#audio-send-metrics) has a direct impact on audio delay, as the metric indicates the round trip time of packets. High latency can result in perceptible delays in audio.

 We recommend a round-trip time of 200 ms or less.
 If the round-trip time is larger than 500 ms, users may experience significant delays that can lead to frustration and hinder effective communication. In such cases, the conversation flow can be disrupted, making it difficult to have a smooth and natural interaction
