Cisco ISR 4321 Router with CME11.5

[critchey880]

I have a Cisco ISR4321 Router currently running CME10.5.  I see on the "Cisco Unified CME 11.5 supported firmware, platforms, memory and voice" that the ISR4321 is listed.  I am trying to figure out the needed IOS-XE to run CME11.5 but it says to use the feature navigator which I can not seem to figure out to answer my question.  Can anyone please enlighten me either how to get my answer from the feature navigator or, more simply, what version I do in fact need of the IOS-XE to run CME11.5. Thanks.

Looks like 16.3.1. Take a look at the S-train column under IOS Release here:

You can find the matrix here:

For CME 11.5 you will need the Denali IOS-XE (16.3.1). Important note about this IOS from CME Admin guide:

Important Information about Cisco IOS XE 16 Denali

Effective Cisco IOS XE Release 3.7.0E (for Catalyst Switching) and Cisco IOS XE Release 3.17S (for Access and Edge Routing) the two releases evolve (merge) into a single version of converged release—the Cisco IOS XE 16 Denali—providing one release covering the extensive range of access and edge products in the Switching and Routing portfolio.
