Chapter 2 Overview of the VoIP Wireless Network VoIP WLAN Configuration Wireless Network Requirements for VoIP When configuring voice over the wireless LAN, use APs that run Cisco IOS Version 12.3(8)JA or later. Controllers should be running version 4.0 and higher with IOS Version 12.3(8)JX or later. The Cisco Unified Wireless IP Phone 7921G supports Cisco Aironet APs (APs) that can run Cisco IOS in autonomous mode and APs that run in lightweight mode with lightweight AP protocol (LWAPP) and use a Cisco Unified wireless LAN controller. Table 2-7 lists the supported AP models and operation mode in the WLAN. Note Voice over the wireless LAN (VoWLAN) does not currently support MESH technology such as Cisco Aironet 1500 Series Lightweight Outdoor Mesh APs. Table 2-7 Supported APs and Modes AP Models Cisco Aironet 350 Series AP Cisco Aironet 500 Series AP Cisco Aironet 1100 Series AP Cisco Aironet 1130 Series AP Cisco Aironet 1200 Series AP Cisco Aironet 1240 Series AP Cisco Aironet 1250 Series AP Cisco Aironet 1300 Series AP Cisco 1000 Series Lightweight AP Autonomous Mode Yes Yes Yes Yes Yes Yes Yes Yes No Lightweight Mode No Yes Yes Yes Yes Yes Yes Yes Yes Note Be aware that Wi-Fi compliant APs 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 APs for Voice This section identifies key AP configuration options that are required for optimal voice performance. This is not a complete list of configuration steps or options for deploying APs such as the Cisco Aironet APs. For more information about configuring your AP, refer to the appropriate Cisco Aironet AP Installation and Configuration Guide for your model or the documentation for your AP. Note When deploying the Cisco Unified Wireless IP Phone 7921G with the World Regulatory Domain (CP-7921GW-K9), you must enable the APs for world mode (802.11d). The world model phone gets the channels and power information from the AP. To see a list of configuration tasks for the Cisco Aironet AP, controller, and Ethernet switch when setting up VoIP on the WLAN, see the "Configuring the Wireless Network" section on page D-1.
