Call Latency Monitoring

Live Latency Monitoring

For real-time latency analysis, you can monitor the IraVoice dashboard, which provides several network and streaming metrics, including:

• SSL handshake time
• WebSocket (WSS) connection delays
• WebSocket socket errors
• Other streaming and network-related metrics

Post-Call Latency Analysis

After calls are completed, latency and quality metrics can be analyzed using the Call Event CDRs received on the webhook endpoint.

The following events are useful:

1. call_quality

This event provides overall call quality information, including:

• MOS (Mean Opinion Score)
• Quality

This helps evaluate the overall user experience for each call.

2. stream_stopped

This event contains detailed stream-level latency metrics within the setup_delays parameter, including:

• Start time
• SSL handshake delays
• Average bot delay
• WSS/WebSocket connection delays

Example

Code
"setup_delays": {
  "started": "2026-05-15T11:39:17.813164Z",
  "resolve": 0,
  "connect": 0,
  "ssl_handshake": 4641,
  "wss_handshake": 36,
  "first_audio": 16,
  "att": 0,
  "awt": 0,
  "abd": 13
}

Unlike the dashboard, which shows averaged metrics across calls, the stream_stopped event provides per-call visibility, making it useful for debugging specific latency issues.
