The following new fields are added to the Extensions page:

- Extension information with status

- Terminal position indicates RPN number and name of the base station.

- State

The following fields no longer display on the Edit Extension web page:

- Forwarding Unconditional Number

- Forwarding No Answer Number

Domain Name Server – Naming Authority Pointer (DNS NAPTR) Support

You use the Name Authority Pointer (NAPTR) to allow the handset to automatically determine and select the appropriate transport protocol for the phone line.

You specify the transport protocol of your choice (UDP, TCP, or TLS) on the base station web page. You set the SIP Transport field on the Servers page to Auto to enable the phone to automatically select the protocol.

When you configure the setting to Auto, the handset determines the transport protocol based on the NAPTR records on the DNS server. The handset uses the protocol specified in the record that has the lowest order and preference. When there are multiple records with the same order and preference, the handset looks for a protocol within the records, in the following order of preference: UDP, TCP, and TLS. The phone uses the highest priority protocol that it finds in a record.

Handset User Interface Enhancements

Users see the following enhancements:

- The handset displays the Cisco logo at startup.

- The handset warns the user when it's too far away from the base station.

- When the handset is in use, the user hears a beep. The Coverage warning field in the Audio Settings menu must be set to On.

- When the handset is idle, the user sees instead of the coverage bars in the top left corner of the screen.

- When the user has a recurrent alarm, the handset identifies that the alarm is recurrent after it sounds for that particular day. The Alarms screen displays the time and weekdays for the recurrent alarm.

OPUS Codec Support

The handsets and base station now support the OPUS codec.

You enable the codec on the Server page of the base station administration page. By default, OPUS doesn't display in the Codec Priority field, so you need to click Reset Codecs to add OPUS to the list.

Cisco IP DECT Phone 6825 Ruggedized Handset

If you need to use the handset in a volatile, dusty, or damp environment, you can use the Cisco IP DECT Phone 6825 Ruggedized Handset. This handset is IP65-rated, which means that the handset is sealed to protect it from dust and water.

The standard handset and ruggedized handset have the same call features. The ruggedized handset has the orange band to differentiate it from the standard handset.

Documentation Changes

Starting with Firmware Release 4.7, updates directly related to the release features are clearly marked in the documents. This change allows users of previous releases to identify content applicable to their release.

For example, the new field, Failover Reconnect Timer, is identified in the Cisco IP DECT 6800 Series Administration Guide as a new field for Firmware Release 4.7.

Firmware Release 4.7 also caused a major revision to two administration web pages. The new version and old version of the sections to describe the pages are contained in the Cisco IP DECT 6800 Series Administration Guide. The new sections and the old sections identify the firmware release and contain cross-references between the sections to assist the user.

Upgrade the Firmware

You can upgrade the base station and handset firmware with TFTP, HTTP, or HTTPS. You upgrade the base station first. After the upgrade, the base station automatically reboots. Then you upgrade the handsets, which automatically reboot.

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

- For the base station, the zip filename starts with IPDECT-DBS210.

- For the standard and ruggedized handsets, the zip filename start with IPDECT-PH6825.

The Firmware Release 4.7 zip files contain files:

- For the base station: IPDect-DBS210.0470MPP-6_REL.zip

- For standard and ruggedized handsets: IPDect-PH6825.0470MPP-3_REL.zip

Note

- 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

- Caller Identification and Other Phone Functions

- Base Station Firmware Downgrade Limitation

- Base Station Alert Due to a Clock Synchronization Error

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.
