802.1x Authentication Configuration Requirement for Autonomous Access Points
If you use an autonomous access point (AP), you must configure the SSID for open + eap and network-eap authentication if using LEAP, EAP-FAST, PEAP, or EAP-TLS.
•
•
The following configuration example allows the Cisco Unified Wireless IP Phone 7925G and 7921G with firmware 1.3(1) and earlier or 1.3(2) and later to authenticate to the autonomous access point successfully.

EAP-TLS and PEAP Support
Cisco Unified Wireless IP Phone 7921G firmware version 1.1(1) and later supports advanced wireless security features such as EAP-TLS and PEAP. If you use EAP-TLS or PEAP for authentication, it is highly recommended that you do not downgrade the firmware because the authentication settings will not be valid on firmware releases prior to 1.1(1) and the phones will lose connectivity to the network.
Note
Note
If you must downgrade the firmware, you need to disable any network profiles that use EAP-TLS and PEAP. If you upgrade to firmware version 1.3(2) again after a downgrade, reconfigure the EAP-TLS and PEAP settings, including any user installed certificates required for authentication.
WLAN IP Address Restriction
It is recommended that you do not use the network 192.168.1.0 /24 for the WLAN. This is the default network used by the USB interface for Cisco Unified Wireless IP Phones. Using this network for the WLAN can cause problems if the USB interface is enabled to use that same network.
Workarounds include changing the WLAN network, changing the USB interface IP address on the phone, or restricting users from charging the phone via the USB interface.
Coexistence (802.11b/g and Bluetooth)
Note
When using coexistence where 802.11b/g and Bluetooth are used simultaneously, consider these limitations and deployment requirements:
•
•
•
•
USB Connection Disabled After Powering Off/On the Phone
If you power off the Cisco Unified Wireless IP Phone 7925G with the USB cable connected and then power it on again, the USB connection might fail.
To enable the USB connection, unplug the USB cable from the phone and then plug it back in.
Auto 802.11a Preferred Over 802.11b/g (Dual Band) Mode
If you configured the 802.11 mode (in Network Profile) as Auto 802.11a preferred over 802.11b/g (dual band), the preferred band (if available) will be used at power-on, but the phone may switch to the less preferred 2.4 GHz band (if available) and the preferred band is lost. Once the phone has connected to the less preferred band, it will not scan for the preferred band if the current band is acceptable, and may remain connected to the less preferred band.
Use in Healthcare Environments
This product is not a medical device and uses an unlicensed frequency band that is susceptible to interference from other devices or equipment.
Unplugging the Headset from the Phone
If the headset plug is removed slowly while a call is active, the call may be disconnected. To avoid an unexpected call drop, disconnect the call before unplugging the headset.
Online Help for the Cisco Unified Wireless IP Phone
Online help for the Cisco Unified Wireless IP Phone 7925G or 7921G is available only for systems with Cisco Unified Communications Manager 7.0 and later. Users can access online help by pressing the center navigation button from the main phone screen.
When users access online help for earlier releases of Cisco Unified Communications Manager, a message states that the online help feature is not available.
Cisco Unified Communications Manager Password Feature and TFTP Encryption
If you are running Cisco Unified Communications Manager 5.1 or later, you must set the password in Cisco Unified Communications Manager Administration on the Phone Configuration window. The password set in Cisco Unified Communications Manager takes precedence over the password that is set on the Cisco Unified Wireless IP Phone 7925G web pages.
Caution
Adjusting the PHY Rate When Using 802.11b and Call Admission Control
If your wireless LAN has access points that use 802.11b and you plan to use Call Admission Control (CAC) with TSPEC, then you must modify the PHY rate to a supported rate for your 802.11b access points.
To modify the PHY rate on the phone web page, follow these steps:
Procedure
Step 2
Step 3
Step 4
Step 5
System Log Trace Files Can Impact Voice Quality
Voice quality can be impaired when you set system log trace files for higher debug levels. Set only the modules that are required when capturing trace files for a phone.
Regulatory Domains for Cisco Unified Wireless IP Phone
You can use a Cisco Unified Wireless IP Phone only within the region in which it is purchased. The Cisco Unified Wireless IP Phone might not function properly in another region, because it is manufactured and sold for specific regulatory domains. For example, domains such as North America and Japan, have regulations that control the radio frequency (RF) channels and transmission power that are available for wireless phones.
You can determine the regulatory domain for your phone by accessing Settings > Model Information > WLAN Regulatory Domain.
Table 1 shows the supported regulatory domains.
Note

http://www.cisco.com/application/pdf/en/us/guest/products/ps5861/c1650/cdccont_0900aecd80537b6a.pdf
Supported Access Points
When deploying voice over the wireless LAN, ensure the autonomous access points have Cisco IOS Version 12.3(8)JEA or later, and controllers have version 4.0 or later.
The Cisco Unified Wireless IP Phone 7925G or 7921G uses Cisco Aironet Access Points (APs) that support Cisco IOS in autonomous mode and APs in unified mode with lightweight access point protocol (LWAPP) that use a wireless LAN controller.
Table 2 lists the supported AP models and their operation mode in the WLAN.
.
Note
Wi-Fi compliant APs that are manufactured by third-party vendors should support the Cisco Unified Wireless IP Phone 7925G, but might not support key features such as Wi-Fi MultiMedia (WMM), Unscheduled Auto Power Save Delivery (U-APSD), Traffic Specification (TSPEC), QoS Basic Service Set (QBSS), Dynamic Transmit Power Control (DTPC), or proxy ARP.
Configuring Cisco Unified Access Points with EAP-FAST
If you are using EAP-FAST with the Cisco Unified Wireless LAN Controller, you must increase the EAP request (802.1x) timeout to a minimum of 20 seconds to enable the phone to receive the PAC credentials successfully.
To change the EAP request timeout, follow these steps:
