New and Changed Features

Cisco IP DECT Phone on CUCM

Now you can deploy Cisco IP DECT Phone 6825 on Cisco Unified Communication Manager. The Cisco IP DECT 6800 Series uses Digital Enhanced Cordless Telecommunications (DECT), a wireless technology. DECT operates at or near the 1.9 GHz frequency and does not interfere with other wireless technologies such as Bluetooth (operates at 2.5 GHz or 5 GHz). The Cisco IP DECT 6800 base station converts IP to DECT. The CUCM has no knowledge of the DECT operations. From the CUCM perspective, the DECT handsets appear as VoIP endpoints.


Note

You must configure DECT base station for TCP. You must not use base station MAC address when you add the DECT to the CUCM. Each Cisco IP DECT Phone 6825 is a separate Third-party SIP device (advanced) on CUCM. For example, if you have 100 6825 handsets, then you will need 100 Third-Party SIP Device (Advanced) devices in CUCM.

Currently, few basic features such as make a call, answer a call, hold, transfer a call, conference are supported.

Configuration Changes Logging

Configuration changes logging feature lets you keep track of the configuration changes that the users make in the base station. You can also track configuration changes of a handset in the similar method. The base memory stores the information about which parameter is changed in the changelog. However, this information doesn't contain the actual details of the changes, but it only stores specific change made in the configuration. After the successful reporting of the changes, the changelog is cleared.

  • Cisco IP DECT 6800 Series Administration Guide

  • XML Reference Guide for Cisco IP DECT 6800 Series

Configuration Change Reporting

When configuration changes of the base station is reported, the base station requests changelogs from the DECT locked handsets. For every locked handset, the base station requests three times with an interval of five seconds. Once requests for all handsets are complete, the changelogs of the base and the handsets are collected, processed, transformed to the correct XML tags. Then these tags are sent to the configuration server. If a handset doesn't respond, the syslog records this behavior. The handset changelogs from the device are cleared only after successful delivery of it to a base station.

EDOS Profile Supports all XML Parameters

Now the DECT base station is able to accept all XML parameters included in the configuration file from the Cisco CDA server (EDOS).

Stateful Firewall to Control Incoming Ethernet Traffic

Now for Cisco IP DECT 110 Single-Cell Base Station and Cisco IP DECT 210 Multi-Cell Base Station, you can enable stateful firewall to control incoming network traffic.

After the firewall is enabled, it analyzes ethernet packets of type IPv4. It then traces the trusted ports for incoming traffic and blocks data packtes from untrusted ports.

Network-Related Information Extraction Using CDP/LLDP

Both CDP and LLDP, which contain VLAN information, are included in this feature implementation. The protocols must be treated differently based on the different packet and content types.

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 upgrade the handsets after the base station upgrade completes. The base station upgrade may take about 30 minutes to 1 hour to complete and reboot. The handset upgrade may take 20-30 minutes to download and verify, and an extra few minutes to load the new firmware file. The handset must be placed in the charger and not removed until the handset loads the firmware file and reboots.

You can upgrade Cisco IP DECT 210 Multi-Cell Base Station to Firmware Release 5.1(2) only if the base station is currently running release 5.0(1) or 4.8(1) SR1. If the base station is currently running release 4.7 or 4.8, you must upgrade the base station to release 5.0(1) or 4.8(1) SR1 before upgrading to release 5.1(2). If the base station is currently running release 4.5, you must upgrade the base station to release 4.6 in factory reset mode before upgrading to release 4.8(1) SR1.

You can upgrade Cisco IP DECT 110 Single-Cell Base Station to Firmware Release 5.1(2) if the base station is currently running release 5.0(1) or 4.8(1) SR1. If the base station is currently running release 4.8, you must upgrade the base station to release 5.0(1) or 4.8(1) SR1 before upgrading to release 5.1(2).

Note

  • If you haven't modified the password in the base station running Firmware version 4.8 or 4.8(1) SR1 and you upgrade the base station, the administration user ID and password change request displays when you login to the base station.

  • From Firmware Release 5.1(2), if you need to downgrade to an earlier release, you can downgrade to the latest branch of the Firmware Release 5.0(1) or 4.8(1) SR1. You must perform a factory reset on the base station to downgrade. This reset will set the administration user ID and password to the default values.

For detailed information about the upgrade or downgrade 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.

After the upgrade to Firmware version 5.0(1), you can downgrade the base station only to the latest branch of the Firmware version 4.8(1) SR1. This downgrade requires you to factory reset the base station. The 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.

Open Caveats

The following caveats are open at the time of the release.

  • CSCwd83296 DECT 110/210: Handset Upgrade Rules can't be overwritten by blank rule from CM services.
