1.3.49 PDN (Primary Directory Number)/SDN (Secondary Directory
Number) 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 exten-
sion. 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 ex-
tension, similar to a DSS button. In addition, this button can be used to perform the following
operations:
•
•
answer calls ringing at the PDN extension
•
hold calls and retrieve calls held by the PDN extension (
•
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.
•
A PDN extension can only receive OHCA or Whisper OHCA from the corresponding SDN
extension. When a call is made from another extension, a PDN extension will receive a call
waiting tone.
•
The button light of each PDN/SDN button shows the current status as follows:
