Analyze Call Quality with the Call Quality Explorer

The Call Quality Explorer is an optional feature that must be enabled. Contact your account representative for more information.

This provides insight into the routing and how calls are connected. It displays information like call events, trunk groups, and devices. You can quickly see the sequence of events during the call, like a missing packets event or a CTI trigger event. Starting with a single contact ID, you can also track any associated IDs or where problematic events continued. If a call has associated IDs, you can also view the call's MegaLadder. This is like the call ladder in Voice Diagnostics, showing the call timeline and server traffic.

  1. Click the app selector icon of app selector and select Monitoring Gateway.

  2. Click Voice Quality Metrics.

  3. Filter the call list:

  4. From the list of calls, click the contact ID you want to analyze. The row expands to show the individual call details.

  5. Locate and hover over the contact ID inside the Call Details tab. A pop-up with several links displays.
  6. Click Call Quality Explorer. The explorer opens in a new browser tab.
  7. Click the contact ID in the list.

Analyze Call Quality with WebRTC Analytics

An interactive page displaying all WebRTC data. You can track basic information like the tenant Closed High-level organizational grouping used to manage technical support, billing, and global settings for your NiCE CXone system., agent application, and locations. You can also see more in-depth data like timelines for jitter or bitrates. Bitrate is the number of bits that are transferred at a time. Higher bitrates transfer more data, but also require more bandwidth.

Your organization must have WebRTC Analytics enabled to use this feature.

  1. Click the app selector icon of app selector and select Monitoring Gateway.

  2. Click Voice Quality Metrics.

  3. Filter the call list:

  4. From the list of calls, click the contact ID you want to analyze. The row expands to show the individual call details.

  5. Click the WebRTC Analytics button WebRTC Analytics button. The analytics opens in a new browser tab.
  6. Review the summary information about the call at the top. This helps you decide which aspects to investigate, like a low bitrate or packet loss from incoming packets.
    WebRTC Analytics overview
    FieldDetails
    Room nameThe contact ID.
    Peer nameThe agent ID.
    OSThe operating system used by the agent.
    BrowserThe browser and version used by the agent.
    Business UnitThe tenant from which the agent handled the call.
    ClusterYour organization's NiCE CXone cluster.
    Agent Console TypeThe agent application that the agent used to handle the call.

    Network TypeThe type of network that the call happened over, like a VPN, wifi, or ethernet.
    ISPThe internet service provider of the agent.
    LocationThe agent's network location.
    Remote locationThe contact's network location.
  7. Review the notifications in the Overview section. These notifications indicate potential issues that you may want to investigate. In the example screenshot, the round trip time (RTT) for the example call has a severe issue. This is the amount of time it took for a request to travel from its origin, to its destination, then back to its origin. A good RTT measurement is below 100 milliseconds. A score above 400 may indicate that the connection was terminated.
  8. Review the channels section. This indicates the incoming and outgoing traffic. The blue arrow pointing toward the headphones indicates incoming audio for the agent. The red arrow pointing away from the headphones indicates outbound audio from the agent. This may indicate if you have download or upload speed issues.
  9. Review the timelines to see when any issues may have occurred. Bitrate and jitter display by default. You can display other data like Round trip time by clicking the timeline labels. Look for any sharp jumps or dips in the timeline. The throughput displays how much bandwidth the call is using.
  10. Click Trace to access errors logged to the console during the call.
  11. Click Advanced WebRTC Analytics to view:
    • webrtc-internals.
    • Active connections in webrtc-internals.
    • webrtc-internals API trace.

Analyze Call Recordings in Voice Quality Metrics

Your organization must have call recording set up to use this feature.

Voice Quality Metrics displays the recording in the Call Visualizer window. This lets you see the recording broken down by time duration, individual speakers, audio waveform, and so forth. You can also skip around the recording while listening. This lets you identify issues with individual participants, verify that quality issues exist, and experience how issues like jitter actually impact the quality.

While listening to a call recording, pay attention to things like:

  • Audio glitches.

  • Cut or one-way audio.

  • Lag or latency causing speakers to talk over each other.
