Matrix PRASAR UCS System Manual 823
If B fails to dial the DND-Override code before the end of the routing beeps, error tone will be played to
him.
Now, to take another example,
• C calls A.
• An error tone is played to C and the DND message 'In Meeting' set by A appears on C’s phone display.
In the above examples, if A has set E’s extension as the Intercept Destination, then calls from B and C will be
routed to E’s extension.
Feature Interaction:
Call Forward: When DND and Call Forward-Unconditional are set on an extension, Call Forward is given priority. If
any other type of Call Forward and DND are set on an extension, DND is given priority. However, if DND with
Intercept Destination is set, it will not work. If an extension has set both Call Forward and DND, then Feature Tone
will be played to the extension user.
If an extension A has set DND with Intercept Destination as E, incoming calls on A’s extension will be routed to E’s
extension.
If E sets Call Forward or DND with Intercept Destination as B, incoming calls from A’s extension will be still routed
to E’s extension. Only incoming calls on E’s extension will be routed to the B’s extension.
How to configure
For this feature to work, 'DND' must be enabled in the Class of Service of the group of the extensions which is to be
allowed this feature.
Also, 'DND-Override' and 'Privacy from DND-Override' can be enabled in the Class of Service of the extensions to
whom this features are to be provided.
Besides these, the System Engineer may program the DND Text Message, Stuttered Dial Tone when DND is set,
Intercept Destination for DND as per user requirements.
The user can then select the type of calls for which he wants to set DND.
Configuring DND in Class of Service
In the default Station Basic Feature Template 01 assigned to all extensions of the PRASAR UCS, the default CoS
group 01 has DND enabled. So, all extensions of PRASAR UCS can set and cancel DND. DND-Override and
Privacy from DND-Override are disabled in the default CoS group 01. So, none of the extensions can use DND-
Override, or be exempt from DND.
While it makes sense to offer all extensions DND, providing DND-Override and Privacy from DND also to all
extensions will not serve the purpose of DND.
Decide which extensions are to be allowed 'DND', which are to be allowed 'DND-Override', and which are to be
allowed 'Privacy from DND-Override'. Generally, DND-Override is allowed to the Operator extension. It may be
allowed to extensions of persons in senior positions in the organization. Similarly, Privacy from DND-Override may
be allowed to persons in senior positions in the organization.
