The CCA 1.6 release is a minor release that has the following feature enhancements:
1) Support for the Unified Communications 500 series phones
2) Support for CUE 3.0 upgrade

In addition to the above, CCA 1.6 also has routine maintenance bug fixes

CCA 1.6 has been tested and is compatible with the UC-520 4.2.7 software pack. A couple of guidelines for the CCA 1.6 release:
1) UC-520 4.2.7 software pack should only be upgraded with CCA 1.6. You can continue to use CCA 1.5 to manage/configure the SBCS solution elements but do not use CCA 1.5 to upgrade to your UC-520 to the 4.2.7 software pack.
2) During the upgrade process on the UC-520 with the 4.2.7 software pack using CCA 1.6, there is a popup "Informational Message" about free flash space (see attached image). Please ignore this message and continue with the upgrade process. CCA 1.6 will ensure that the upgrade goes through successfully by freeing up required flash space.

The CCA 1.6 release is backwards compatible with previous CCA releases.
