This chapter explains the steps required to configure voice and video services on a W-IAP for Voice over IP
(VoIP) devices, Session Initiation Protocol (SIP), Spectralink Voice Priority (SVP), H323, SCCP, Vocera, and Alcatel
NOE phones, clients running Microsoft OCS, and Apple devices running the Facetime application.

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, 802.11b, 802.11g, and 802.11n 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 59:
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.
