So I just installed a new 7835 to our cluster as a Subscriber and everything went well (I had to wipe it as it had 7.1(5) and we have 7.1(3)). I got the PAK that came with it, registered, got the license file and uploaded it successfully to the Publisher. My problem is that I still can't add the new subscriber to a Call Manager Group. It's not listed in the list of available servers. Anyone know what might be the cause? I'm pretty sure I registered the PAK correctly. I put the MAC of the Publisher node which is what it told me. Was I supposed to put the MAC of the new server instead? Please help!
Have you already enabled and started the CCM service??
Only nodes that are running the CCM service show up as options for the CUCM group.
Licensingwise all your licenses need to be issued with the PUB MAC address.
If you go to licensing you should see how many node licenses you have. You need 1 per every server you want to run the CCM service.
If this helps, please rate
