New and Changed Information

The following sections describe the features that are new or have changed for this release.

MIDlet Minimize to Background When Power On

The MIDlet Minimize to Background When Power On feature enables the phone to automatically launch a Java MIDlet in the background when the phone powers on. The MIDlet automatically launches and then minimizes to the background after the phone registers to the Cisco Unified Communications Manager.

To launch the MIDlet, the phone must subscribe to the MIDlet application. If the phone is not subscribed to the MIDlet, the automatic MIDlet launch fails.

The administrator configures the Idle URL field for the phone to contain the URL to the MIDlet application, followed by a space and the flag -minimize. For more information, see the Cisco Unified Wireless IP Phone 7925G, 7925G-EX, and 7926G Administration Guide.

The user can close the automatically-started MIDlet. To restart the MIDlet at a later date, the user can manually start the MIDlet or turn the phone off and back on.

The feature is supported on the following phones:

  • Cisco Unified Wireless IP Phone 7925G
  • Cisco Unified Wireless IP Phone 7925G-EX
  • Cisco Unified Wireless IP Phone 7926G

          Important Notes

          This section provides general information about using and supporting the Cisco Unified Wireless IP Phone 7921G, 7925G, 7925G-EX, and 7926G in your system.

          Health-Care Environment Use

          This product is not a medical device and uses an unlicensed frequency band that is susceptible to interference from other devices or equipment.

          Debug Level Impact to 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.

          USB Connection Disabled After Powering Phone Off and On

          If you power off the Cisco Unified Wireless IP Phone 7921G, 7925G, 7925G-EX, and 7926G 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.

          Game MIDlet Impact to Voice Quality

          If you are running a Java MIDlet game application in the background during an active call, voice quality may be affected.

          Upgrade from Releases Prior to 1.4(3)

          If your Cisco Unified Wireless IP Phones are currently running a release prior to 1.4(3), then you must use the Trivial File Transport Protocol (TFTP) method to upgrade to release 1.4(3) or later. Once upgraded to release 1.4(3) or later, you can then upgrade to later versions using the phone's webpage either via USB or WLAN.

          Unified Communications Manager Endpoints Locale Installer

          By default, Cisco IP Phones are set up for the English (United States) locale. To use the Cisco IP phones in other locales, you must install the locale-specific version of the Unified Communications Manager Endpoints Locale Installer on every Cisco Unified Communications Manager server in the cluster. The Locale Installer installs the latest translated text for the phone user interface and country-specific phone tones on your system so that they are available for the Cisco IP Phones.

          To access the Locale Installer required for a release, access http:/​/​software.cisco.com/​download/​navigator.html?mdfid=286037605&flowid=46245, navigate to your phone model, and select the Unified Communications Manager Endpoints Locale Installer link.

          For more information, see the "Locale Installer" section in the Cisco Unified Communications Operating System Administration Guide.


          Note


          The latest Locale Installer may not be immediately available; continue to check the website for updates.
