Introduction
This Release Note describes the updates and fixes in version 7.5.6(XU) of the Cisco SPA525 firmware.
As with any firmware release, read these release notes before you upgrade the firmware. Cisco also recommends that you back up the configuration before you perform any firmware upgrade.
Note
There are two SPA525G/SPA525G2 firmware versions. One of them contains updated Bluetooth firmware (identified by -bt in the filename). The updated Bluetooth version is larger in size and takes longer to install (about 3 to 4 minutes). If the Bluetooth firmware version you are using is below 0.00.34, we recommend that you install the -bt version of this firmware. To see which Bluetooth version is installed on your phone, view the Bluetooth Firmware Version parameter in the Info tab in the web management interface
Note The hardware identified by serial number CCQ18160L03 or later supports 128mb flash and only can load firmware 7.5.5b or later.

Behavior During Times of Network Congestion
Anything that degrades network performance can affect voice and video 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
To reduce or eliminate any adverse effects to the devices, schedule administrative network tasks during a time when the devices are not being used or exclude the devices from testing.
