Installing SSL Certificates on CUCM/UCCX/CUPS

[Quintin.Mayo]

We have the following versions for the below appliances.

Call Manager version is 10.5.2.12901-1
UCCX version is 10.6.1.11001-31 (ES08-40)
IM & Presence version is 10.5.2.22900-2

 We want to install certificates on all devices, my questions are below.

Q1: When installing the certification on our Publisher and Subscriber, is a separate certificate required for each server or they use the same certificate?

Q2: Our the UCCX device, when loading a certificate is it automatically consumed by al of the components? or are there steps for applying to each?

Not sure about UCCX, but on CUCM/IM&P it will depend on whether you're using multi-san or not, if you use one per cluster, per service, or individual certs per server, per service.
