In Device Profiles, you create new device profiles and manage existing ones. Each Device Profiles is a collection of 1 or more XML attributes that can then be applied to a Tag. There are two different types of device profiles: Polycom Pre-Installed Defaults and User Created Profiles. When you install EZ UDM Pro you will have the Polycom Pre-Installed Defaults available for use. The admin may choose to use them as is or modify the values to suit their needs. Note that UDM Pro supports ALL standard Polycom XML commands, which are parsed out during the firmware upload, but non-standard/user created commands are also supported.

Note! If you navigate to another selection in EZ UDM Pro from the Device Profiles – Add New dialog page without saving your changes, you are warned that you are exiting the page without saving your changes. You are given the option to Cancel and return to the Device Profiles – Add New dialog or Proceed and discard the changes you have made. The same notification is displayed if you select (in the upper right corner) Cancel instead of Save to exit the page.
