User's Manual

controller 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 controller cannot get the quality information from the RTCP
frames.
Important Points to Remember
RTCQA for voice calls is supported only in the following cases:
l when the signaling messages are not encrypted.
l when the signaling messages are encrypted for Lync.
l when the voice client does not roam from one controller to another controller. In other words, when a client
moves to a foreign agent controller, 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 913
