We started using an IP Office 500 v2 with a UC module in July of last year and our experience with the one-x portal has been pretty terrible. We started off with version 9.1.1 and we were unable to get a connection to the presence server so our business partner upgraded us to 9.1.2. We ran into a few other issues with VMPro and the UC module so Avaya shipped us a new module and our business partner installed it and upgraded us to 9.1.3. After that we were able to connect but it was pretty unreliable. People would show as being on the phone when they were not, etc. and the users would need to log out and back in to fix it. I noticed that issue was fixed in a recent tech bulletin so I upgraded us to 9.1.6 over the weekend and now the one-x service randomly restarts about once a day. Is the software really this unstable or is there some other issue in my setup?
