I have a client using CUCM 4.1.3 SR2. The cluster has a PUB, SUB1, SUB2.
They have EM configured with the EM Service URL pointing to SUB2.
But the EM service is not activated in both the SUB, its running only on the PUB. EM works all fine, user is able to login, logout.
Can someone explain how this is working?
