Document Revision 4C
When DND and Call Forward are set on the same telephone, call forwarding works. If Busy

If an extension already receiving forwarded calls activates DND option 4, callers to the

forwarded extension hear DND tone.
If an extension activates DND option 4, other extensions can still forward calls to it, but the

callers hear DND tone.
An extension user can override Call Forwarding or Do Not Disturb at another extension

using any of the following methods:
1. Program 11-12-01 Service Code Setup (for Service Access) – Bypass Call
(default: 707)
2. Program 11-16-06 Single Digit Service Code Setup – DND/Call Forward Override Bypass
(default: No Setting)
3. OVRD Softkey


programming even if the extension is forwarded.
