New and Changed Features
This release doesn't have any new feature. This firmware release only includes bug fixes.
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) SR1 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)SR1. 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)SR1 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)SR1.

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.
