I am new to cucm, but I would check the status of the licenses.
I read that when licenses are in question (changed NIC or something), it will run for 30 days while you get it corrected.
I don't know beyond that, but it only takes a few seconds to check license status.

When you said Subscriber in your first message, did you mean as in 'Publisher/Subscriber" ? If so, then you should be looking at your Node Licenses. Do you have a license for each server ?
