Using Device Settings Groups, you can manage some configuration data for Avaya terminals. The device settings are associated with groups or a default group and can be assigned to one or more terminals or locations.
Device Settings Groups of type Location Groups can be associated with Locations and Device Settings Groups of type Terminal Groups can only be associated with a terminal having a Terminal Group ID. When a terminal is set up for the first time, the terminal is pre-provisioned with the Default Group. The Default Group provides the global settings across locations and terminals.
A terminal can be individually associated with a set of device settings that are downloaded and set according to the following criteria:
The configuration of a terminal is set as Default Device Settings if the terminal:
Does not belong to an Routing Policy Location.
Does not belong to the Network Routing Policy Location where the terminal is located.
Is not associated with a specific set of Personal Profile Manager (PPM) attributes.
The configuration of a terminal is set as the set of attributes defined for a Routing Policy Location if the terminal:
The configuration of a terminal is set as a specific set of PPM attributes if the terminal is individually associated with a set of PPM attributes and the selected set of PPM attributes exists.
Priority order for using the device settings data is as follows:
Terminal group data – highest priority. This priority is used if a terminal group is configured in the endpoints.
Location based settings. Has priority over default settings.
Default service settings.
PPM supports device settings on a per location basis. Session Manager notifies an endpoint when device settings are modified, including the following settings:
Timers: Registration, Subscription
QoS parameters: For Video, Audio and call control
VLAN ID
Time zone
