I followed the link in the above document but when I get to the UC520 software loads section, there is not a new version of the UC520 software. The older 7.0.3 software is still posted as the most recent. I am probably reading the post incorrectly, but I expected to see new software with version 7.1 on the download link. I was able to pull CCA 2.1, and we'll be giving that a go soon.
The Early Adopter Software Pack is supported on UC 520 and CCA. Please note that the Early Adopter Software Pack bundles latest Software and Hardware features available in point product releases (IOS software, Voicemail software, Phone firmware, etc). Since CCA may not support all the new features, the pack is not tested in detail with CCA. However, the features that are already supported in CCA function just fine. Both, the Early Adopter Software Pack and the Default Software Packs are supported by our support team.
So this is in fact an EA Pack for UC520 so you can enjoy the new phones primarily (SPA5xx). The Default Release / Factory release will come closer to Mid October for UC520.
The UC540 Launched today and I just asked Saurabh when the UC540-7.1.3.zip will be posted and he said very soon...
Do you have the new phones to try? If not, perhaps wait for the default release....
Scroll all the way down. Its there..... :-)))))
