Configure base settings for managed phones under FENT

Before you can create a managed phone for operation under a FENT (Far-End NAT Traversal) deployment model, you need to create a customized base settings configuration for the phone. The base settings configuration contains a group of settings found on the Base Phone and Base Line Appearance tabs in Phone Management and defines how a particular phone is to operate in PureCloud. Once you create a base settings configuration, you can create and configure a phone.
