New and Changed Feature

This release doesn't have any new feature. It provides downgrade compatibility for the future release.

Upgrade the Firmware

You can upgrade the base station and handset firmware with TFTP, HTTP, or HTTPS. You upgrade the base station first and then update the handsets after the base station update completes. The base station upgrade may take about 30 minutes to 1 hour to complete and reboot. After the base station upgrades, you can then upgrade the handsets. The handset upgrade may take 20-30 minutes to download and verify, and an extra few minutes to load the new firmware file.

Note

You must place the handset in the charger and not remove until the handset loads the firmware file and reboots.

You access the Cisco Software Download page to get the firmware in zip files. The zip files contain these files:

  • For the base station, the zip filename starts with:

    • IPDect-DBS110 for Cisco IP DECT 110 Single-Cell Base Station.

    • IPDect-DBS210 for Cisco IP DECT 210 Multi-Cell Base Station.

  • For the handset, the zip filename starts with:

    • IPDect-PH6823 for Cisco IP DECT Phone 6823 Handset.

    • IPDect-PH6825 and IPDect-PH6825RGD for Cisco IP DECT Phone 6825 Handset and Cisco IP DECT Phone 6825 Ruggedized Handset.

Note

As you upgrade your handset and base station, note the following items:

  • If you upgrade the base station from Firmware Release V460B1 or earlier, the administration user ID and password reset to the default values.

  • After you install this load and then need to downgrade the release to Firmware Release V460B1 or earlier, you must perform a factory reset on the base station. This reset will set the administration user ID and password to the default values.

For detailed information about the upgrade procedure, refer to the "Maintenance" chapter in the Cisco IP DECT 6800 Series Administration Guide.

Limitations and Restrictions

System Behavior During Times of Network Congestion

Anything that degrades network performance can affect phone system voice quality, and in some cases, can cause a call to drop. Sources of network degradation can include, but are not limited to, the following activities:

  • Administrative tasks, such as an internal port scan or security scan

  • Attacks that occur on your network, such as a Denial of Service attack

Caller Identification and Other Phone Functions

Caller identification or other phone functions have not been verified with third-party applications for the visually or hearing impaired.

Base Station Firmware Downgrade Limitation

After the upgrade for V460 B4, a downgrade of the base to a firmware version earlier than V460 B2 requires you to factory reset the base. This factory reset will reset the login credentials to the defaults. If you don't perform the factory reset, you can't log into the administration web pages.

Base Station Alert Due to a Clock Synchronization Error

The base station self-check process fails if there’s a clock synchronization error. When this error occurs, the LED on the base station flashes red, amber, and green. In this case, we recommend the standard RMA process.
