Voice Quality Metrics

Voice Quality Metrics provides access to call quality data in CXone. It monitors SIP Protocol used for signaling and controlling multimedia communication sessions such as voice and video calls. voice traffic and agents' WebRTC sessions. You can access useful call data like the ISP, location, average bit rate, and average round trip time (RTT). This information helps you troubleshoot call quality issues for both contact and agent call legs The portion of an interaction that takes place between CXone and the agent.. Voice Quality Metrics saves this call quality data for each contact ID A unique numerical identifier assigned to each contact. for 30 days.

This application helps you identify contact IDs that have call quality problems. To dig deeper into issues and find exact causes, you can combine Voice Quality Metrics with these other features:

CXone Voice Diagnostics: This lets you view in-depth call data at the level of individual call legs. It helps you pinpoint exactly where a call issue may have occurred in the connection. For example, you can see a breakdown of each RTP stream for the call. You can also review the call ladder A diagram that provides in-depth details about a call's traffic, like individual server communications, SIP information, requested URIs, and so forth. to see which servers had connection issues.
Call Quality Explorer: 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.
WebRTC Analytics: An interactive page displaying all WebRTC data. You can track basic information like the business unit High-level organizational grouping used to manage technical support, billing, and global settings for your CXone system., agent application, and locations. You can also see more in-depth data like timelines for jitter or bitrates.

Call Quality Metrics

Voice Quality Metrics uses metrics and data from a variety of sources, including:

Metrics from the CXone voice network collected via monitoring probes. These include mean opinion score (MOS), R-factor, jitter, and packet loss .
Quality of service measurements for both the CXone network and the external network. This makes it easier to determine the source of voice issues. An overall average call quality is also provided for each contact ID.
Call-related data from the ACD like agent name, skills Used to automate delivery of interactions based on agent skills, abilities, and knowledge., contact IDs, call disconnect reasons, and so on.
Filter capabilities to determine quality of service performance by business segment, like teams, skills, POC The entry point that an inbound contact uses to initiate an interaction, such as a phone number or email address.s, or agents.
If you have call recording set up, you can review the recordings and view a breakdown of the recordings.

Call Score

One primary method of assessing call quality is the call score. A score is assigned to each contact ID. Voice Quality Metrics calculates the score based on its mean opinion score (MOS). This is a numeric score that indicates the quality of the call from the user's perspective. The score ranges from 1 (lowest) to 5 (highest). It's calculated using transport data gathered from the media streams, both upstream and downstream. The data include bandwidth, jitter, latency, and packet loss.

Voice Quality Metrics uses the following standards to define call quality for each contact ID:

MOS	COLOR CODING	CALL QUALITY
4.3 to 5.0	Green	Excellent
3.5 to 4.2	Blue	Good
3 to 3.4	Orange	Moderate
0 to 2.9	Red	Poor

Jitter

In networking, jitter refers to small, intermittent delays during data transfer. Many things can contribute to jitter, such as:

Network congestion.
Network collisions.
Signal interference.

A jitter value greater than 99 MS can result in packet loss, which can mean lower voice quality.

JITTER (MS)	COLOR CODING	CALL QUALITY
0 to 30	Green	Excellent
31 to 99	Blue	Good
100 to 149	Orange	Moderate
150	Red	Poor

Packet Loss

In networking, packet loss happens when a transmitted packet does not reach its destination. Routers or switches can drop packets due to network congestion. Packets can also be discarded by the jitter buffer. The more packet loss a call experiences, the lower the call quality.

PACKET LOSS (%)	COLOR CODING	CALL QUALITY
<1	Green	Excellent
<1 to 2.9	Blue	Good
3 to 5	Orange	Moderate
>5	Red	Poor

R-Factor

R-factor is another measure of call quality that Voice Quality Metrics considers. R-factor is calculated based on factors such as jitter, delay, and packet loss.

R-FACTOR	COLOR CODING	CALL QUALITY
90 to 100	Green	Excellent
80 to 89	Blue	Good
70 to 79	Orange	Moderate
0 to 69	Red	Poor

Voice Quality Metrics Interface

Screenshot showcasing elements of the product interface, like the filter, call details, and so forth.

Interface Element	Details
1 - Load Criteria	These options let you view data for a specific business unit High-level organizational grouping used to manage technical support, billing, and global settings for your CXone system. and time range. Specifying this information helps you filter and find call segments faster. By default, Voice Quality Metrics displays calls and call data for the last hour. You can pull calls for up to 30 days in the past. The global filter lets you limit the calls that you request from the database. Instead of displaying every call from your time range, then filtering the list, the global filter limits the database query. This makes your search fast and convenient, helping to speed up troubleshooting. For example, you can specifically query the database for calls with poor quality, only WebRTC calls, and so forth. From the three dots menu, you can also: Hide Tiles: You can choose how many tiles appear at the top. Export Data: You can export call data as a CSV file. The export function can export all 46 data columns but is subject to the filters applied on the page. When you've chosen the business unit High-level organizational grouping used to manage technical support, billing, and global settings for your CXone system. and date range for which you want to view calls, a progress bar appears to show you where you are in the loading process.
2 - Call List Filter	This section lets you filter the call list. It contains the following elements: Free Text Search: You can use a free text search to find specific contact IDs or a range of contact IDs that contain a specific number. You can also use it to search for other data that is part of the selected columns, such as agent name, POC The entry point that an inbound contact uses to initiate an interaction, such as a phone number or email address., and so on. If no results are found within the returned dataset, you can use the Advanced Search link to search records for contact IDs from the last 30 days. Filter: You can filter the call list based on criteria you define. You can filter by a variety of details like media type A medium, such as voice, email, and chat, through which a contact connects with an intended recipient., ACD or agent attributes, or specifically agent leg The portion of an interaction that takes place between CXone and the agent. or contact legs. Columns Selector: You can select the columns of data that appear about calls in the call list. Seven columns display by default, but you can display up to 46 in total.
3 - Summary Tiles	Shows the quality of voice calls, including MOS, average packet loss, and jitter. It displays a pie chart that shows the breakdown of call quality based on the MOS value. It also shows the distribution tile for call directions data. This includes, DefaultOutbound, AgentLegDefault, InboundPOC, and BlindXfer. If any tiles have an arrow, you can click this arrow to filter the call list according to the options presented. For example, you can choose to display only calls with excellent, good, moderate, or poor quality.
4 - Call List & Contact Records	Lists every call record within your filter or search parameters. From this list, you can expand each row to view more in-depth information.
