Hello - Have been running CallManager 18.104.22.1680-2 for about 2 years. Have a primary callmanager and secondary. When it was set up the default callmanager group had the primary listed first and the secondary (subscriber) listed second. So - all devices (shows about 300 devices) are registering with the publisher and not the subscriber which I understand is the preferred method. So, if I set up a second callmanager group (default is the only one there now) and reverse the order of the two servers (so subscriber is listed first and publisher second), and then change the device pool groups to use this newly created CM group, and then reset those phones, they should register with the subscriber first, and the publisher as a standby. Does this sound corect? And is there anything that would happen when I do this that I should be aware or? I want to make sure I don't have adverse effects from doing this?
Also, should I have all devices register with the subscriber or should I split them up so some register first with the publisher. Again, the callmanager group default shows 356 devices.
