Enabling Real Time Call Quality Analysis
Real Time Call Quality Analysis (RTCQA) enables the switch to compute the call quality parameters such as jitter,
delay, packet loss, and call quality score (R-value) directly from the RTP media stream. Additionally, the switch
saves the periodic samples of the quality parameters for detailed analysis of the results. You can monitor up to
30 active calls that are initiated after enabling RTCQA. You can avail the full benefits of RTCQA by setting the AP
in tunnel, decrypt-tunnel, or split-tunnel forwarding mode.
Enabling RTCQA is helpful in cases where the VOIP clients do not use RTP Control Protocol (RTCP) or use
encrypted RTCP (in the case of Lync) which the switch cannot get the quality information from the RTCP
frames.
Important Points to Remember
RTCQA for voice calls is supported only in the following cases:
n when the signaling messages are not encrypted.
n when the signaling messages are encrypted for Lync.
n when the voice client does not roam from one switch to another switch. In other words, when a client
moves to a foreign agent switch, RTCQA does not take effect.
You can use the WebUI or CLI to enable RTCQA and view the call quality reports based on the analysis.
To generate Lync UCC score, you must enable RTCQA. For more information on UCC score, see UCC Call Quality
Metrics on page 961
