I am looking for a specific document that is pointing to difference between cisco call manager version 9.1 and 10.5 in terms of features.
also is their any ready snapshots available for installation of CUCM 10.5
The version specific SRNDs are the best guides to know what is the new addition into any major release (e.g. difference between 9.x and 10.x) and the difference between the minor releases and bug fixes (e.g. 10.5.2 and 10.5.2 SU1) are better documented in the Read Me documents (available where you can download the ISOs as well as any optical media for the software)
Installation of 10.5.x is as similar as any other CCM 8.x/9.x/10.x, it is virtually same even the look and use is same, except for the new features
[+5] to Wilson for sharing his views.
you can refer the link
Also, refer the attachment showing comparison.
Thanks Aman for the link (ATE CCM 10.x) this is the first time I am looking at that. Didn't even occur to me all these days to search for that. (+5)
And thank you very much for the Endorsement, it is really appreciated.
