Explanation:
Device pools are user configurable sets of defaults that are assigned to devices as a single function. The devices then inherit all the settings from the device pool that they are assigned.
This can be used to scale and simplify the distribution of CallManager groups, which are discussed below. A device pool allows primary attributes to be assigned globally to a device. The required components for a Device Pool are: Device Pool Name, CallManager Group, Date/Time Group, Region, Softkey Template, SRST Reference. Some optional fields are: Calling Search Space for Auto-Registration, Media Resource Group List, User Hold MOH Audio Source.
