Management Groups
Proceed as follows:
• Using the Configuration Manager (page Groups > Phone numbers)
Phone number
This is an internal number. You can select any of the numbers in the internal supply of phone numbers. This number is then used for distributing calls and can be called directly by an internal subscriber. (Select  New to enter.)
* Note: A number cannot be allocated twice.
* Note: Using numbers with few digits (two- or three-digit numbers) inevitably restricts the possible supply of numbers that require more digits. For example, if the phone number 12 is assigned, the phone numbers 120 to 129 and 1200 to 1299 are no longer available.
* Note: The default exchange line access number on the PBX is 0 in the factory settings. However, this can be changed. Note that changing the exchange line access number restricts the phone numbering plan.
Name
Freely selectable name. This name is used to identify the group within the PBX and the connected system phones. The name can also be transferred to the VoIP end devices via LDAP server.
Property Configure
Opens the configuration of the group.
Filter:
The list of groups is filtered by the entered or selected value.
 New
Adds a new group. You must then make the settings for this new group.
* Note: Up to 64 groups can be created.
 Delete
Deletes the entries marked in the list.
