Once a call is connected, the goal is not accomplished. The next challenge becomes audio quality. Are you able to quickly identify devices in your network that are experiencing quality issues? Or, if someone is complaining of poor quality, can you confirm the problem?

Choose Your View of Audio Quality
Metrics like MOS, latency, packet loss and jitter help identify devices in your network that are experiencing quality issues so you can diagnose the source of the problem and correct it. But, where do you begin? Having the flexibility to slice and dice audio quality visibility how you choose—by IP address, extension, device type, codec or even call path—is a good starting point. Let’s take a quick peek at a few of these options, starting with by IP address.

By IP Address
A chart like Audio Quality by IP Address & Subnetworks below highlights audio quality performance by device IP address and subnetworks for a defined time period. This showcases devices and domains that are performing well across the enterprise while also indicating which devices and networks have poor call quality scores. The three charts show the top fifteen (15) entities based on number of connections.

In the search for problem areas, you will want to be able to filter the data set to select only marginal and poor audio quality options to quickly see the devices with the most problems during a selected time interval.

To troubleshoot, you can drill down to see the call detail so you can discern if the driver of the problem is packet loss, jitter and/or latency. And you can determine if the problem is restricted to a set of IP addresses and/or date ranges.

By Codec
Another interesting view into audio quality is by codec. You can highlight audio quality performance by codec to showcase the codecs that are performing well across the enterprise while also indicating which codecs have poor call quality scores. Charts like below display trending by voice server/switch so can identify trends and quickly spot any anomalies. Clearly G7.111 codecs are showing higher quality performance than G.729 options.

By Voice Server by Month
As mentioned above, trending analytics can be very insightful. A higher level perspective is simply by voice server by month. A quick glance can show the trends over time by switch platform.  Maybe you have a particular problem with one of your platforms.

By Extension
If a specific caller in your organization is complaining about call quality or if you want to proactively validate the caller experience for specific extensions within your organization (such as executives or call center agents), the ability to quickly search by extension is critical. Leveraging dashboard filters to pinpoint your search criteria for date ranges, phone numbers and/or quality ratings makes the task much more efficient than trying to decipher raw record files.
