824 Matrix ETERNITY NE System Manual
B has DND-Override in his Class of Service, C does not have this feature.
DND Text messages as well as Voice Message Notification for DND have been programmed by the System
Engineer.
• A has set DND on his extension with the DND Text message 'In Meeting'
138
.
• B calls A.
• As B has DND-Override, the Voice Message for DND Notification is played to B once, and 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 either during
the Voice Message or 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.
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.
• As C has a SLT, C will get only the Error tone.
• But as Voice Message for DND Notification is programmed in the system, C will be played the pre-
recorded message once.
• Since C is not allowed 'DND-Override' in his Class of Service, he cannot exercise this feature during the
Voice Message.
• At the end of the voice message, C will be played error tone.
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 or DND with Intercept Destination is set along with Call Forward-Unconditional 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, DND
with Intercept Destination 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.
138. While DND and DND Text Message can be set from any phone, DND Text Message can be viewed on Extended IP Phone only.
