1.3.49 PDN (Primary Directory Number)/SDN (Secondary Directory Number) Extension

When performing SDN Direct Dial to call the corresponding PDN extension, the SDN button light shows the current status of the destination extension as follows:

Green on: You are using the line.

Red on: The line is being used. (The PDN extension, or another SDN extension when multiple extensions have SDN buttons to a same PDN extension, is using the line.)

Even if a PDN extension has set Do Not Disturb (DND), you can call the extension as normal by pressing the SDN button.

When an SDN button is in Standard SDN Key Mode, you can dial a telephone number while hearing a dial tone, instead of pressing the SDN button again. Depending on system programming, your call will be made using either your normal calling privileges (Class of Service) or those of the corresponding PDN extension (SDN Walking COS).

Call Hold and Call Hold Retrieve

You can put calls answered with a PDN or SDN button on hold normally (1.3.6 Call Hold).

You can also retrieve a call held at your extension/another extension with a simple operation, regardless of the call type.
