Correct Cucm locale installer to CUCM 10.5

[mdrangell22]

Hello

I have a CUCM 10.5.2.12901 and I want to install it some locale to have the correct idiom on my phones but I am not sure which to install because I don't see that version under callmanager locale installer page.

I just see the versions: 10.5(2.3000), 10.5(2.2200-1), 10.5(2.2000-1), 10.5(2-1000-1) and 10.5(1.1000-1) so which version is the correct to me? is there any website with compatibility matrix?

Go through Readme File. Suported  firmware versions are mentioned in Readme file. you can use 10.5(2.3000)

Hello

You say I can use 10.5.(2.3000) but I don't understand the following:

In the readme file it says 7861 FW is 10.2(1) but by default CUCM 15.2.12901 7861 comes with 10.3.1.12 so with this mismatch the locale installer will work? Also I don't see the 7811 FW information in any locale

FW 10.2(1) will be the minimum requirement . you can use 10.5.(2.3000). 

78XX use common firmware.
