I have a brand new Presence server, and I am not sure what to do with it. Is tieing it in with an LCS server a requirement? ANother thing I found is if a phone subscribes the PhoneMessenger service, and is not on the same subnet as the server, it does not recieve broadcast messages from the server. Does it use Multicast for that? I have it integrated with the Callmanger 5 server, but I am not entirely sure just what this thing does, it is part of our lab setup along with meetingplace, Unity and CCM 5, all of which are working fine.
