Note Be aware that Wi-Fi compliant access points that are manufactured by third-party
vendors can function with the Cisco
Unified Wireless IP Phone 7921G, but might
not support key features such as Dynamic Transmit Power Control (DTPC),
ARP-caching, LEAP/EAP-FAST, QBSS, U-APSD, 802.11d and 802.11h.
Configuring the Wireless Network for Voice
This section identifies key access point (AP) configuration options that are
required for optimal voice performance. This is not a complete list of
configuration steps or options for deploying access points such as the Cisco
Aironet Access Points. For more information about configuring your access point,
refer to the appropriate
Cisco Aironet Access Point Installation and Configuration
Guide for your model or the documentation for your access point.
Note When deploying the Cisco Unified Wireless IP Phone 7921G with World
regulatory domain (CP-7921G-W-K9), you must enable the access points for
world mode (802.11d). The world model phone gets the channels and power
information from the access point.
