If you take the Unify technician training classes you will get a copy of the HTML version of the AMO manual, and a lot of other manuals, but you CAN sign up for an and user account on the unify portal and it will give you access to most of the system documentation manuals you can download, and minor things like phone firmware upgrades and sometimes certain clients (but not the HTML version of the manual because it's a whole directory full of files). To get access to the knowledge base and the software that matters you need to have the login for the "technician" portal (partner portal). In addition, by creating an accont on the end user portal you also get access to Unify's own forums, that are not only supported by people like us, but are also monitored by Unify staff, and you can also get things like security bulletin notices and other related things.
Also note that if your system is running 4000 V6 or V7.1 you can login to the system portal on your 4000 (typically the IP of that is 1 address lower than the assistant, so if Assistant is 10.1.3.123 the portal might be 10.1.3.122. Note when you try to access the portal you need to use HTTPS:// - the system portal has all of the documentation for the system once you get in there. I know it got broke in V7R2 so none of the help stuff works right and I am not sure if that got fixed in a future hotfix, or if it never got fixed in V7R2. V5 and lower do not have the portal.
More on topic, it has been my experience with the 4000 that if you set up a phone that has, say, a Prime line key, and 2 secondary line keys so you have a total of 3 lines on that phone, it will nOT matter which of the 3 line keys that you press - the phone will give out the number of the Prime Line key (usually bottom button) of that phone as the caller-id info (at least to outside calls).
