I need an expert's opinion on upgrading our 2801's IOS.
We currently running IOS 12.4(6)T3, CME 3.4(0),CUE 2.3.4.
I would like to upgrade the IOS because of a bug we ran into (CSCsd58707). I see that 12.4(22)T has this bug fixed, and it also lists CME 3.4 as a supported feature.
Is it OK to upgrade to 12.4(22)T while leaving the CME and CUE at the current version?
Generally speaking is the version on the CME compatibility matrix (12.4(6)T in this case) the ONLY version the should be used or is it the minimum recommended version?
Thanks in advance.
It's fairly odd because 12.5 has actually become part of 12.4(15)T I believe. We aren't expecting to see 12.5 for a long time, since 12.4(15)T is expected to go to something like 12.4(15)T20 or so.
I can check this later for you.
If you upgrade to 22T, CME is automatically upgraded. You would need to download the CME files for the GUI and phone loads though.
