Wireless Network Requirements for VoIP

The Cisco Unified Wireless IP Phone 7925G 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 2-8 lists the supported AP models and operation

mode in the WLAN.

When configuring VoWLAN, use APs that run Cisco IOS Release 12.3(8)JA or later. It is recommended

that Cisco Aironet 1130AG, 1240AG, 1250 series APs run Cisco IOS Release 12.3(4g)JA1 or later.

Controllers should be running version 4.0217.0 (minimum) or version 4.2.61.0 or later, which is

recommended. The controllers should have Cisco IOS Release 12.3(8)JX or later configured also.

Note Voice over the wireless LAN (VoWLAN) does not currently support MESH technology such as Cisco

Aironet 1500 Series Lightweight Outdoor Mesh APs or third-party APs are not supported.

Note Be aware that Wi-Fi compliant APs that are manufactured by third-party vendors can function with the

Cisco

Unified Wireless IP Phone 7925G, 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.
