Using a PDN/SDN Button
1.5.1
Primary Directory Number (PDN)/Secondary Directory
Number (SDN) Extension
Primary Directory Number (PDN) buttons and Secondary Directory Number (SDN)
buttons are useful when extension users will handle calls for other extensions. For
example, a secretary or multiple secretaries can handle calls and check the call status of
a boss or multiple bosses. The functions of PDN and SDN buttons are as follows:
PDN button: This button can be used to make and receive all calls (including both outside
and intercom calls). Having multiple PDN buttons allows multiple calls to be queued at the
extension. Extensions that have a PDN button are called PDN extensions.
SDN button: The light of an SDN button displays the current call status of the registered
extension, similar to a DSS button. In addition, this button can be used to perform the
following operations:
•
call the PDN extension (SDN Direct Dial)
•
answer calls ringing at the PDN extension
•
hold calls and retrieve calls held by the PDN extension (Call Hold and Call Hold
Retrieve)
•
transfer calls to the PDN extension (Call Transfer Using SDN Button)
Extensions that have an SDN button are called SDN extensions.
•
The extension that is registered as the destination of an SDN button must have at least one
PDN button.
•
One extension can have up to 8 PDN buttons.
•
An extension can have only one SDN button for each PDN extension.
•
The button light of each PDN/SDN button shows the current status as follows:
