Hardware Diagnostics
Cisco Unified Wireless IP Phones are frequently returned and a replacement is requested when the phone
is operational. In firmware 1.3(4), a self-diagnostic tool is available to determine if a valid hardware
issue exists.
You can access the Diagnostics menu from the Phone Settings menu, where the Keypad, Speaker,
Microphone and WLAN Radio and Antenna can be validated.
The WLAN diagnostics menu is the standard site survey utility, which will use the current network
profile information to scan for the configured network.
Bulk Deployment Utility
Firmware release 1.3(4) introduces the bulk deployment utility for Cisco Unified Wireless IP Phone
7925G and 7921G. This utility may be used to provision the phones if they have the same security
settings (i.e. WPA2-PSK) or if they have unique 802.1x accounts.
Two deployment methods are supported—Default and Bulk. The bulk deployment method requires that
a CSV file is imported containing the MAC address, username, and password. A configuration file is
created using the CSV file and the common credentials (SSID, Security mode, 802.11 mode, etc.). When
using the bulk deployment method, the username and password apply to Network profile 1 only.
The Bulk Deployment Utility does not support EAP-TLS or PEAP with server validation because it does
not support certificates.
PEAP, without server validation, is supported using the Bulk Deployment utility. If a server validation
is required, you must import the server certificate using the phone and enable server validation in the
network profile via the phone web page.
Note
The bulk deployment utility can support a CSV file with a maximum of 1000 entries.
Note
The Bulk deployment utility requires firmware release 1.3(4).

Interband Roaming
Interband Roaming allows a Cisco Unified Wireless IP Phone to seamlessly roam between 2.4 GHz and
5.0 GHz bands. This feature allows you to configure the phone for an Auto 802.11 mode (i.e. Auto-RSSI,
Auto-a, or Auto-b/g) that will scan both bands during an active call and will use a less preferred band if
the preferred band is no longer available.
Interband roaming is leveraged for various scenarios:
•
5 GHz indoor and 2.4 GHz outdoor
•
Migrating from 2.4 GHz to 5 GHz
•
2.4 GHz footprint but 5 GHz band for critical areas only (5 GHz cannot provide adequate coverage
for all areas.)
When a phone is idle, it may scan, depending on the scan mode configured in the Unified CM. If the
phone is configured for automatic scan mode, the Cisco Unified Wireless IP Phone will not scan until
the current signal reaches the scan threshold. At this point, it will scan both bands.
If the phone if configured for continuous scan mode, an idle phone may scan both bands depending on
the number of 2.4 GHz neighbors that are available. If enough neighbors are available and there is a 2.4
GHz candidate with an adequate signal, the phone can possibly stop scanning 5 GHz (active channel
parking) and roam to 2.4 GHz to preserve battery life.
The Auto-RSSI logic is also used when the phone is idle and is configured for an Auto 802.11 mode and
continuous scan mode. If the 2.4 GHz signal reaches the scan threshold, the 5 GHz channel scanning will
resume. If there is an inbound or outbound call, the phone can temporarily roam to 5GHz, if available.
However, the phone can roam to 2.4 GHz after the call is terminated if the channel parking criteria is met.
Before firmware release 1.3(4), both bands would be scanned only at power up or if the current band was
lost if configured for an Auto 802.11 mode. Because of this, there was no seamless roaming since the
current band would have been disconnected before the target band could be discovered. Also, there was
a possibility that the phone could stay connected to the less preferred band (i.e. connected to 2.4 GHz
when it is configured for Auto-A mode and a good 5 GHz signal is available).
Full CCKM Support
Cisco Centralized Key Management (CCKM) reduces the amount of delay time by centralizing the key
management, which reduces the number of key exchanges. To optimize secure roaming, CCKM can be
enabled while in WPA or WPA2 mode.
Prior to this firmware release, CCKM was not supported when WPA2/AES was selected; this required a
full re-authentication when roaming between access points, and could result in loss of audio during the
roam. Now that CCKM is supported when WPA2/AES is selected, the full re-authentication is no longer
required and roaming to a new access point should not result in any perceptible loss of audio.
Firmware 1.3(4) provides full CCKM support of all WPA versions.

Supported Access Points, page 9
Battery Life After Returning From Out of Range State
The Cisco Unified Wireless IP Phone may have a short battery life after returning from the out-of-range
state. The battery life can be two to four hours long if the IP phone travels out of range for up to three
to five seconds, and then returns in range of the configured network without rebooting the IP phone.
This may occur with IP phones using firmware release 1.3(4), but not with any earlier release. If your IP
phone experiences a short battery life after it has operated out-of-range for a few seconds, you can reboot
the IP phone. The out-of-range alert may be enabled in Unified CM to provide a notification anytime the
IP phone leaves the service area. For more information of the status of this operation, refer to
CSCtf82507, using the Software Bug Toolkit.
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—5.2.193.0 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)

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.
