New and Changed Information

The following information is introduced in Cisco Unified Wireless IP Phone firmware release 1.3(3):

Dynamic PHY Rate

802.11 Default Mode

Auto Line Select

Firmware Downgrade Restrictions

New Radio Signal Status Indicators

Coexistence Improvement and Increased Call Capacity

Support for New Country Codes on Cisco Unified Wireless IP Phone 7925G

Prompt Mode for WLAN Credentials

Dynamic PHY Rate

In release 1.3(3) , a dynamic PHY rate is used instead of the static PHY rate of earlier releases. The default PHY rate is still 12 Mbps, but if that rate is not enabled on the access point (AP), then the Wireless IP Phone will try the next highest data rate enabled on the AP. Supported PHY rates on Cisco APs are 5.5, 6, 11, 12, or 24 Mbps.

If an 802.11b AP is used, the highest available date rate would be 11 Mbps. If a data rate of 11 Mbps is already enabled on the phone, that data rate will automatically be used without any configuration change needed.

The dynamic PHY rate is also useful for other types of deployments. For example, high capacity deployments may only have 24 Mbps and higher data rates enabled. With previous releases, you would need to manually change the PHY rate to 24 from the default of 12 in order for CAC to work. With release 1.3(3), the change to 24 Mbps (in this case) is made automatically.

If 12 Mbps is not enabled on the AP, you must ensure that the next highest data rate is 24 Mbps (which is supported). For example, if 12 Mbps is disabled but 18 Mbps is enabled, the phone will try the next highest rate of 18 Mbps and fail because that rate is not supported.

802.11 Default Mode

Beginning with release 1.3(3), the default 802.11 mode is Auto-a; the default 802.11 mode for earlier versions is Auto-RSSI.

Using Auto-a, the phone associates to 5 GHz, if available. With Auto-RSSI, the phone associates to the frequency with the strongest signal—typically 2.4 Ghz.

Auto Line Select

Auto Line Select is a feature that will enable a user to select whether a new incoming call will be brought into focus. This feature applies to multi-line scenarios where a user on a call can shift the focus to an incoming call on a different line. This feature is disabled by default, and if disabled, it will shift the call focus for incoming calls on the same line only—call waiting.

In order to enable this feature, a devpack or Cisco Unified Communications Manager update is required.

Firmware Downgrade Restrictions

The 1.3(3) firmware introduces a restriction on downgrading to earlier firmware revisions. It is strongly recommended that this firmware is validated for use in a network to ensure full compatibility before implementing this firmware into production.

Changes in the memory industry, coupled with analysis of some memory corruption, have necessitated a change to some memory drivers and power management algorithms. If it does become necessary to downgrade to an earlier version of firmware, please contact the Cisco Technical Assistance Center in order to learn details of the necessary steps to downgrade.

New Radio Signal Status Indicators

Beginning with release 1.3(3), additional radio signal status indicators will be displayed on the phone to provide more information about the connection status. The bars indicate the signal strength for the Access Point to which the phone attempts to associate.

—RF signal is available, but does not match any of the WLAN profiles.

—RF signal is available, matches a WLAN profile, and the phone is attempting to authenticate.

—The phone is authenticated to a valid WLAN profile.

Coexistence Improvement and Increased Call Capacity

Coexistence is when the Cisco Unified Wireless IP Phone 7925G uses a Bluetooth handsfree device— headset or speaker, while operating in 802.11b/g mode. There are no Coexistence concerns while operating in 802.11a mode.

Release 1.3(3) provides improvements in the handling of Coexistence between Bluetooth and 802.11b/g. As a result, call capacity for the Cisco Unified Wireless IP Phones has increased.


Note The call capacity numbers in the following table are for one access point or channel.


802.11 Mode

Four concurrent calls


Support for New Country Codes on Cisco Unified Wireless IP Phone 7925G

Release 1.3(3) adds support for these country codes:

United Arab Emirates (AE)

Vietnam (VN)

Oman (OM)

Prompt Mode for WLAN Credentials

The Wireless IP Phones now provide the Prompt Mode feature. This feature is enabled only for the English locale. If enabled, a prompt for WLAN authentication credentials is displayed upon first bootup for the first network profile only. If Prompt Mode is enabled, the username is stored in flash, but the password is not stored and must be entered each time the phone is powered on.

The username can be overridden during the prompt for the user credentials.

If the login screen is dismissed, a softkey is displayed for logging in, or for using a different enabled network profile.

Supported Access Points

Configuring Cisco Unified Access Points with EAP-FAST

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.

Firmware 1.3(1) or earlier, network-eap is required (for Cisco Unified Wireless IP Phone 7925G and 7921G)

Firmware 1.3(2) or later, open eap is required (for Cisco Unified Wireless IP Phone 7925G and 7921G)

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.

dot11 ssid voice
vlan 21
authentication open eap eap_methods
authentication network-eap eap_methods
authentication key-management wpa cckm

Power-Off Date and Time for Cisco Unified Wireless IP Phone 7925G

If you turn off the phone (without removing the battery) and then turn it on again, the current date and time will display on the phone screen during power-on, even before the phone connects to the access point and registers with Cisco Unified Communications Manager.

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 Firmware release 1.2(1) and later supports PEAP with the server validation option.



Note A downgrade attempt to a firmware release earlier than 1.1(1) will be blocked if a current enabled profile is configured for EAP-TLS or PEAP.


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 1.1(1) or later 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 This section refers to the Cisco Unified Wireless IP Phone 7925G only.


When using Coexistence where 802.11b/g and Bluetooth are used simultaneously, consider these limitations and deployment requirements:

Capacity—Only up to four bi-directional RTP streams using 802.11b/g or up to seven bi-directional RTP streams using 802.11g per access point or channel are supported.

Battery Life—There can be up to 40-50% reduction of battery life when on call and using Coexistence.

Multicast Audio—Multicast audio from Push To Talk (PTT), Music on Hold (MMOH) and other applications are not supported when using Coexistence.

Data Rate Configuration—It is advised to only enable 802.11g (OFDM) data rates (that is > 12 Mbps) to prevent from engaging in CTS for 802.11g protection, which can impact voice quality.

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 When setting the Administration Password in the Product Specific Configuration section in Cisco Unified Communications Manager 5.1 Administration, you must enable TFTP encryption. Otherwise, the password appears in readable text in the phone configuration file and can be viewed from any host that has access to TFTP server.

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.
