822 Matrix PRASAR UCS System Manual
• DND when set/canceled from the SA mode, will not depend on the assigned CoS.
• The system supports only single-point DND with Intercept Destination, which means, if the destination
extension has also set DND with Intercept Destination, the call will not follow the forwarding path.
How it works
For this feature to work,
• you must select the “DND Call Type”.
• you may select the “Intercept Destination for DND”.
• you may select the “DND Text Message” as per your requirement.
DND Call Type
The extension user/Operator can select the type of calls to be restricted while enabling DND. They can select either
All, Internal or External Calls.
Intercept Destination for DND
If the user wants that the calls are attended to even if DND is set, System Engineer must configure the Intercept
Destination for the user. Incoming calls landing on the extension that has set DND will be routed to the Intercept
Destination. This destination can be the users own mailbox or another extension.
DND Text Message
A DND Message is a short Text Message such as 'In a Meeting', 'In a Conference', 'On Vacation'.
When setting DND (also DND-Remote), the extension user/Operator can select an appropriate text message to be
displayed to the calling extension.
This DND text message is displayed on the calling extension, only if the calling extension is an Extended IP Phone.
The PRASAR UCS supports 9 different DND Text Messages, out of which 8 messages can be changed as per user
requirement by the System Engineer. User can select and set on their phones any of the DND messages
programmed by the System Engineer.
Let us understand this feature with an example:
A, B and C are extension users.
B has DND-Override in his Class of Service, C does not have this feature.
DND Text messages have been programmed by the System Engineer.
• A has set DND on his extension with the DND Text message 'In Meeting'.
• B calls A.
• As B has DND-Override, the DND message 'In Meeting' set by A appears on B's phone display. B gets
routing Beeps.
• To exercise DND-Override, B must dial '4' the feature access code for 'DND-Override' during the routing
Beeps.
• B gets Ring Back Tone, if A's extension is free.
• B gets Busy Tone, if A's extension is busy.
• However, if A has Privacy from DND Override, B will get error tone and the DND message set by A
appears on B's phone.
