3. Click a specific call entry to open the Endpoint voice quality panel.

This view presents voice quality data for individual calls, grouped into the following categories:

• Local: Displays local call information: Timestamp, Call Id, Session desc, From, To, Endpoint, Jitter, Packet loss, Latency, Burst gap loss, PublicIpAddr, LocalAddr, RemoteAddr, QualityEst
• Remote: Displays call route information: Start time, Call Id, Session desc, From, To, Endpoint, Jitter, Packet loss, Latency, Burst gap loss, PublicIpAddr, LocalAddr, RemoteAddr, QualityEst
• Report: Displays server and network information: Call Id, BID, Proxy Server, Relay Server, To Endpoint Relay, To Endpoint Time, From Endpoint Relay, From Endpoint Time

You can adjust filters, columns, and views to prioritize specific metrics.

Filtering options

Sort column values

Sort data in any column alphabetically or numerically:

• Click the arrow icon in the column header to reorder values.

Voice Quality (VQ) Score is calculated from the Mean Opinion Score (MOS), which reflects the quality of human speech on a scale from 0 to 5.

VQ Score	MOS Score
Excellent	4.0 to 5.0
Good	3.0 to 4.0
Fair	2.5 to 3.0
Poor	0.1 to 2.5
N/A(NA)	0.0 or 127

Additional metrics

• Call Volume Ratio = Call volume / Average call volume.

  A ratio over 1 indicates a higher-than-average call load.

• Poor Quality Ratio = Poor calls / Total calls

  Lower ratio = better overall call quality.

The Call Quality Details page provides granular and summary-level call performance data.

Includes:

• Average Call Quality Score: Displays the quality of human speech at the destination of the circuit.
• Total calls and score breakdown: By Excellent, Good, Fair, Poor and N/A
• Call Quality Detail table: Displays individual calls with score, timestamps, extension, owner, and more.

To learn more, see Glossary: Call Quality Details.

The following table displays some of the most important parameters in a voice quality report.

Column	Description
Score	Mean Opinion Score (MOS) rating of voice quality
Start	Start time of the call
End	End time of the call
Ipbx ID	Identifier of the phone system
Extension	Phone system extension number involved in the call.
User Name	The assigned user of the phone system extension number
Site ID	The ID of the site where the call was received
Site Nume	Custom name of the site from the 8x8 Admin Console for the call’s destination
Peer Number	The IP address, port, and SSRC of the session peer, as seen from the remote endpoint that measures performance
NLR%	Network packet loss ratio, in percentage
JDR%	Packet ratio discarded from the jitter buffer, in percentage. Packet Loss occurs primarily due to handling jitter
JBN	This is the current nominal jitter buffer delay in milliseconds, which corresponds to the nominal jitter buffer delay for packets that arrive exactly on time. Added latency occurs primarily due to handling jitter.
Call Audio Codec	Real-Time Transport (RTPReal-time Transport Protocol) payload indicates Codec usage.
User device Details	Endpoint device model and firmware information
Call Origin Location	The originating location for the call
Origin Public IP	The Public IP address of origination
Route Location	The next location in the call path route
Route IP	The Public IP address of next location in the call path route
