Hey guys... so we successfully upgraded from IPO R9.0 to R10.1, and in doing so - some of our users are no longer able to use their Avaya IP Softphones. So we are trying to migrate them to Avaya Communicator (using release 2.1.4). I can successfully login to the Avaya communicator and am able to make/receive calls - however, it comes up with "No Presence" and of course the messaging features, as well as the contacts list is not working. I have verified that I have the presence server address set to the IP address of our One-X portal server, and verified that message & presence is all working via one-x? I am not sure what I am missing. Does the presence/contacts require Web Collaboration? Also, this is a stand-alone ipo on R10.1 and a windows server 2008 R2 running One-X portal 10.1.
