Hi all,

Currently I have a single CUCM and UCCX on the cluster. I am going to add the second CUCM and UCCX in the cluster. What are the licence requirements and the steps for the installation of second CUCM7.0.

Hi Ali,

You will need to aquire a new License for the second "node" that will become your new Subscriber, contact licensing and tie the new "node' license to the existing Publisher MAC address.

Ensure that you have the appropriate number of licenses to support adding a new node.

The "Step by Step" is explained in the link below

I have a first CUCM 7.0 with the following licenses.

LIC-CM7.1-7816=License CM 7.0   7815/7816 Appliance, 500 seats1
LIC-CM-DL-10=Unified CM Device   License - 10 units5

Now I have the second the CUCM 7.0 and the licence that I have for this is

LIC-CM7.0-7816=License CM 7.0   7815/7816 Appliance1

Do this license fullfil my requirement or I need more licenses? I have to upload this license on a second node or on the first one? I have to generate this license with the MAC of first node or with the MAC of second node?

And from where we can update the CTL file?
