ILS Configuration between different version of Cisco CUCM

[KhammariAsma]

Hello,

is it possible to make ILS configuration between two clusters on different version ?

Cluster 1: version 11.5

Cluster 2 : version 14

Thanks in advance

We run it between 12.5 and 14, so that works. Very likely it will work between your versions as well. Have you tried setting it up and got any issue(s) with it, or have you not come to that stage yet?

I have configured ILS between CUCM 11.5 and CUCM 14.0 without any issues before.

I have ILS working between CUCM 10.5 and CUCM 12.5.
