Voice and Video
This chapter the steps required to configure voice and video services on a W-IAP for Voice over IP (VoIP)
devices, including Session Initiation Protocol (SIP), Spectralink Voice Priority (SVP), H323, SCCP, Vocera, and

Wi-Fi Multimedia Traffic Management
Wi-Fi Multimedia (WMM), is a Wi-Fi Alliance specification based on the IEEE 802.11e wireless Quality of Service
(QoS) standard. WMM works with 802.11a, b, g, and n physical layer standards.
WMM supports the following access categories (ACs):
l
Voice
l
Video
l
Best effort
l
Background
The following table shows the mapping of the WMM access categories to 802.1p priority values. The 802.1p
priority value is contained in a two-byte QoS control field in the WMM data frame.

Table 54:
WMM AC to 802.1p Priority Mapping
In a non-WMM or hybrid environment, where some clients are not WMM-capable, you can configure an SSID
with higher values for best effort and voice ACs, to allocate a higher bandwidth to clients transmitting best
effort and voice traffic.
