User Guide for the SIP-T42G IP Phone
The system administrator can assign a private line to boss in one of the following
situations occurs:
The boss doesn't want to miss important calls denied by his DND status.

The boss doesn't want the delegate to answer some important or confidential calls

for him.
The boss wishes his friends and families to reach him directly or bypass his

delegate.
In many organizations, bosses have administrative secretaries who answer their office
phones for them. This is easily accomplished on the Skype for Business Server by using
call delegation. As a result, if one people dial the primary line of the boss, the phones of
the delegate will ring simultaneously. If the people dial the private line of the boss, only
boss's phone rings.
