Call Quality Monitoring Overview

Yeastar P-Series PBX System supports real-time call quality monitoring for extensions during calls and provides call performance reports with detailed metrics, helping technical support diagnose and troubleshoot call issues more efficiently. This topic describes the requirements, key features, and workflow of call quality monitoring.

Note: Yeastar implements call quality monitoring based on the ITU-T G.107 E-model. The performance metric values are provided for reference only, and may vary due to differences in calculation methods.

Requirements

To implement call quality monitoring, make sure both PBX Server and Linkus App meet the following requirements.
PBX Server
Item Requirement
Subscription Plan Enterprise Plan or Ultimate Plan
Firmware Version 37.23.0.123 or later

Feature highlights

QoS-based call quality monitoring
Monitor call quality based on industry-standard Quality of Service (QoS) metrics for comprehensive network performance assessment.
Aggregated call performance report
Well-rounded QoS report provides an overall assessment of call quality as well as granular analysis across different dimensions, and per-call call quality report with detailed performance metrics.
Timely anomaly alert
The built-in Poor Call Quality Reminder event can automatically be triggered to send notifications when poor call quality is detected during calls.
Efficient diagnosis and troubleshooting
Quickly identify which leg of a call is experiencing quality issues for faster diagnosis and troubleshooting.

Workflow

  1. Enable call quality monitoring for extensions from the centralized PBX admin portal, or grant extension users permission to configure the feature from their own Linkus UC Clients.

    When the specified extension is on a call within a specified time period, call quality data is automatically collected to generate a per-call call quality report and aggregate into the extension-wide Quality of Service (QoS) report.

  2. Access call report for further analysis.
    Note:
    • As an administrator, you can access both the overall QoS report and individual call quality reports from admin portal.
    • For extension users, they can access individual call quality reports from Linkus UC Clients.
