I trying to upgrade a UC520 which was delivered with 12.4.11XW to the newest ios release (required for call accounting and SNR). When I try to download 12.4.20T2 which is marked as latest release, cisco recommend to download 12.4.20T3. 20T3 is deffered, also all newer 12.4.22T and 12.4.24T.
So when will a new ios release available for the UC520? On the other hand, I could download a complete software package (7.0.3) for the UC520 which includes the 12.4.20T2 ios. Why is it still available in this package, when it is not available as seperate download?
Go here (you can get to this by searching the community for 'software download'):
Accept EULA then come to the page with all the bundles.
Scroll alllllll the way down :-))))))) Its hiding down at the bottom.....
For the UC500, we are doing solution testing. Some of the IOS was deferred simply because it wasn't solution tested and should never have been released. There isn't anything inherently wrong with those IOS versions, just they didn't meet our testing requirements for the software packs we are using for the UC500. That is why they are not available.
For SNR, the 7.0.3 software pack will not work. It is a CME 7.1 feature and requires a 7.1.X software pack. This means that the 12.4.20 code would not work for SNR. The software in the 7.1.3 EA pack is currently 12.4.22YB. You can also download it individually from cisco.com as well. It is under the All Releases section.
