The password set in Cisco Unified CallManager takes precedence over the password that is set on the Cisco Unified Wireless IP Phone 7921G web pages.


Caution When setting the Administration Password in the Product Specific Configuration section in Cisco Unified CallManager 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 Cisco Unified Wireless IP Phone 7921G 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

Regulatory Domains for Cisco Unified Wireless IP Phone 7921G

You can use a Cisco Unified Wireless IP Phone 7921G only within the region in which it is purchased. The Cisco Unified Wireless IP Phone 7921G 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

Regulatory Domain Number
Geographic Region

Wi-Fi compliant APs that are manufactured by third-party vendors should support the Cisco Unified Wireless IP Phone 7921G, but might not support key features such as Dynamic Transmit Power Control (DTPC), ARP-caching, LEAP/EAP-FAST, or QBSS.

Configuring Cisco Airespace Access Points with EAP-FAST

If you are using EAP-FAST with Cisco Airespace technology, 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 Airespace controller or controllers.

Step 2 Enter config advanced eap request-timeout 20.

Step 3 Enter save config.

Step 4 Enter y to confirm.


Battery Reading Calibration

Firmware release 1.0(3) provides a new mechanism to provide accurate battery reading by incorporating information collected by battery reading calibration at production.


Note Once the Cisco Unified Wireless IP Phone 7921G is upgraded to firmware release 1.0(3), it cannot be downgraded to earlier versions.


Firmware release 1.0(3) provides an automatic battery reading calibration mechanism when IP Phones are not calibrated for battery reading at production and the user experiences short battery life,

To calibrate the Cisco Unified Wireless IP Phone 7921G battery, follow these steps:

Procedure


Step 1 Press the RED key to turn off the power on the Cisco Unified Wireless IP Phone 7921G.

Step 2 Plug in an AC adaptor to the IP Phone.

Step 3 The automatic battery reading calibration will complete within one minute after the charging LED on the phone turns solid green.



Note To confirm the IP Phone has been calibrated for battery reading, choose Settings Menu > Status Menu > Firmware Version Menu. The Boot Load ID field under the Firmware Version Menu indicates the IP Phone has been calibrated. If the Boot Load ID ends with *, the IP Phone has not been calibrated. (For example, BL-P202-E995FCF0* is a non-calibrated IP Phone; BL-P202-E995FCF0 is a calibrated IP Phone.)

Documentation Updates

The following text replaces the "Voice Quality Deteriorates While Roaming" subsection under the "Symptom: The Wireless IP Phone Does Not Roam Properly" section in Chapter 9, "Troubleshooting the Cisco Unified Wireless IP Phone 7921G" of the Cisco Unified Wireless IP Phone 7921G Administration Guide for Cisco CallManager Release 4.1, 4.2, 5.0 and Later.

Voice Quality Deteriorates While Roaming

Check the RSSI on the destination access point to see if the signal strength is adequate. The next access point should have an RSSI value of -67 dBm or greater.

Check the site survey to determine if the channel overlap is adequate for the phone and the access point to hand off the call to the next access point before the signal is lost from the previous access point.

Check to see if noise or interference in the coverage area is too great.

Check that signal to noise ratio (SNR) levels are 25 db or higher for acceptable voice quality.
