Cisco Cucm 9.1 Iso Download High Quality

sir, thanks to you that i completed the installation of cucm on vmware. I would be obliged if you help me resolve this problem. I have created a cluster consisting of a publisher and a subscriber along with tftp. I have enabled the publisher to act like subscriber to register ip phones and i want the ip phone to be registered on the subscriber by default. But the problem is that they are getting registered on the publisher and not on the subscriber. How can I troubleshoot this?
