Managing a Massive Voice Infrastructure with Cisco Prime Collaboration

Cisco IT monitors and manages a huge voice infrastructure, with over 200,000 UC endpoints, and the Cisco Prime Collaboration solution helps us do this work efficiently.

For example, a common problem for my team is identifying which devices are provisioned in the Cisco Unified Communications Manager (Cisco UCM), but are no longer in use. This issue is getting more complex as Cisco employees have multiple devices associated with their one directory number. In a typical case, a salesperson might have a desk phone and a Cisco TelePresence personal video endpoint in the office, another phone in their home office, and use Cisco Jabber clients on a laptop and smartphone at home, at customer sites, or while traveling. Cisco Prime Collaboration lets me easily view this information and verify that the employee is actively using all of these devices.

Hardware phones in particular can become inactive when an employee leaves or transfers and no one else moves to that desk. Cisco Prime Collaboration lets me easily identify and remove that phone. We can also detect which employees haven’t downloaded the latest Jabber client version and encourage them to update their devices to the currently supported software.

Cisco Prime Collaboration gives me a very easy graphical interface to see into the whole global network, and then allows me to drill down to any components to see what’s going on.

How Cisco Keeps Quality High For Voice Calls, Part 2: Metrics

In Part 1 of this post, I described how Cisco IT addresses the first key question—about reporting on voice service availability. In this Part 2, we’ll cover the second question: How does the call sound to all of the connected parties?

Cisco IT Metrics for Measuring Call Quality

Although it seems counter-intuitive, the best source of information about voice quality may not be the people who were on the call. Of course, user trouble tickets about problems such as static and echo can be important indicators of bigger issues in a voice system. But we often find that users don’t report voice quality issues, so additional tools are needed.

How Cisco Keeps Quality High For Voice Calls, Part 1: Availability

Measuring the quality of voice calls that are carried across a corporate network often comes down to just two key questions:

1. Availability: Will calls go through the first time and every time?

2. Quality Metrics: How do we know how well the call sounds to all of the connected parties?

In this two-part post, I’ll describe how Cisco answers these questions through the tools and processes we use for monitoring voice call quality.
