UCC Call Quality Metrics
Computing the call quality metrics is an important aspect of troubleshooting. The metrics enable
administrators to get an idea of the quality of service on the network and troubleshoot network congestion
whenever required. ArubaOS 6.3.x provides UCC call quality metrics for Lync/Skype for Business voice calls
only at the end of the call. In addition to capturing call quality metrics at the end of the call, ArubaOS 6.4.x
captures call quality metrics for active calls. The call quality metrics are extended to voice, video, desktop-
sharing, and file-transfer applications.
A new metric, UCC score is introduced in ArubaOS 6.4. UCC score computes the quality of voice calls. It takes
delay, jitter, and packet loss of RTP packets into account. UCC score is computed on a scale of 0 to 100. This
feature works in tunnel, decrypt-tunnel, and split-tunnel forward modes. To compute the UCC score, you must
enable RTP Analysis on the master controller. Issue the following CLI commands:
(host) (config) #voice real-time-config
(host) (Configure Real-Time Analysis) #config-enable
Table 222 shows the call quality parameters displayed on the controller for various UCC ALGs.
