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.
