Cisco Unified Wireless IP Phone 7925G Configuration Utility Requirement for Wavelink Server

For firmware release 1.3(1), Cisco Unified Wireless IP Phone 7925G Configuration Utility (7925CU) version 1.3(1) is required for using the Wavelink Avalanche server to configure the phone.


Note If you use the Wavelink Avalanche Management Console to configure your phone, be aware that the Cisco Unified Wireless IP Phone 7925G Configuration Utility (CU) is labeled as 7921G, but the CU works for the both phones.


Important Notes

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

Coexistence (802.11b/g and Bluetooth)

USB Connection Disabled After Powering Off/On the Phone

Auto 802.11a Preferred Over 802.11b/g (Dual Band) Mode

Use in Healthcare Environments

Unplugging the Headset from the Phone

Online Help for the Cisco Unified Wireless IP Phone 7925G

Cisco Unified Communications Manager Password Feature and TFTP Encryption

Adjusting the PHY Rate When Using 802.11b and Call Admission Control

System Log Trace Files Can Impact Voice Quality

Regulatory Domains for Cisco Unified Wireless IP Phone 7925G

Supported Access Points

Configuring Cisco Unified Access Points with EAP-FAST

Coexistence (802.11b/g and Bluetooth)

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

Capacity—Only up to two bi-directional RTP streams per access point / 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 7925G

Online help for the Cisco Unified Wireless IP Phone 7925G 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.

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 1 Access the web page for the phone. Refer to the "Accessing the Web Page for a Phone" section in the 7925G Administration Guide.

Step 2 Choose the network profile that you want to configure.

Step 3 Click the Advanced Profile link at the top of the page.

Step 4 In the TSPEC Setting area, change the Minimum PHY Rate to a supported rate, such as 11 Mbps.

Step 5 Click Save to make the change.


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 7925G

You can use a Cisco Unified Wireless IP Phone 7925G only within the region in which it is purchased. The Cisco Unified Wireless IP Phone 7925G 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.

Table 1 Supported Regulatory Domains

CP-7925G-W-K9



Note When deploying the Cisco Unified Wireless IP Phone 7925G with World regulatory domain (CP-7925G-W-K9), you must enable the access points for world mode (802.11d). The world model phone gets the channels and power information from the access point.


For more information about supported regulatory domains, go to the Wireless LAN Compliance Status page at this URL:

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 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 Voice over the wireless LAN (VoWLAN) does not currently support MESH technology such as Cisco Aironet 1500 Series.


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:

Procedure


Step 1 Use SSH or Telnet to access the Cisco Unified Wireless LAN Controller.

Step 2 Enter config advanced eap request-timeout 20.

Step 3 Enter save config.

Step 4 Enter y to confirm.
