Important Notes

This section provides general information about using and supporting the Cisco Unified Wireless IP Phone 7925G in your system:

USB Connection Disabled After Powering Off/On the Phone

Use in Healthcare Environments

Increasing the Debug Level in Trace Settings Can Impact Voice Quality

Supported Access Points

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.

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.

Increasing the Debug Level in Trace Settings 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.

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 uses Cisco Aironet Access Points (APs) that support Cisco IOS in autonomous mode and APs in unified mode that use a Cisco wireless LAN controller.

The minimum and recommended code versions for the LAN controller and the Access Points are as follows:

Cisco Unified Wireless LAN Controller

Minimum—4.0.217.0 or later

Recommended—6.0.196.0 or later

Cisco IOS Access Points (Autonomous)

Minimum—12.3(8)JEA2 or later

Recommended—12.4(10b)JA3 or later (Does not apply to 1100, 1200, 1230)

Table 1 lists the supported AP models.

.

Table 1 Supported Access Point Models

Access Point Models

Cisco 500 Series

Cisco Aironet 1100 Series

Cisco Aironet 1130 Series

Cisco Aironet 1140 Series

Cisco Aironet 1200 Series

Cisco Aironet 1230 Series

Cisco Aironet 1240 Series

Cisco Aironet 1250 Series

Cisco Aironet 1260 Series

Cisco Aironet 1300 Series

Cisco Aironet 3500 Series



Note Voice over the wireless LAN (VoWLAN) via Outdoor MESH technology (Cisco 1500 series) is not supported.


Third-party access points are not supported since there is no interoperability testing with these access points. However, as long as the access point supports the key features and follows the standards, the Cisco Unified Wireless IP Phone should be compliant.

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.
