A user wants to ensure that callers from the voice VLAN and callers from the PSTN are directed to a voice mailbox if the line associated with the user’s dn is in use.
Which of the following settings in the Call Forward and Pickup Settings section of the UCM Administration Directory NumberConfiguration page would enable this behavior? (Select 2 choices.)
- Forward All
- Forward Busy External
- Forward Busy Internal
- Forward No Answer External
- Forward No Answer Internal
- Forward Unregistered External
Of the available choices, the Forward Busy External setting would forward public switched telephone network (PSTN) callers to a voice mailbox if the line associated with the user’s directory number (dn) is in use. Similarly, the Forward Busy Internal setting would forward callers from the voice virtual LAN (VLAN) to a voice mailbox if the line associated with the user’s dn is in use. The Cisco Unified Communications Manager (UCM) Administration Directory Number Configuration page enables a UCM administrator to configure several settings related to dns, including the following: call forwarding, call pickup, call waiting, line display text, ring settings, and voice mailboxes.
The Forward Unregistered External setting in the Call Forward and Pickup Settingssection of the UCM Administration Directory NumberConfiguration page would direct a caller from the PSTN to voice mail if that caller attempted to connect to an extension that does not exist on your company’s Voice over IP (VoIP) network. In contrast to the Forward Unregistered External setting, the Forward Unregistered Internal setting would forward internal callers to a specific voice mailbox if the internal caller dialed a nonexistent dn.
The Forward All setting forwards all callers, internal or external, to a specific voice mailbox. This is the same behavior as the CFwdAll softkey that appears on a Cisco IP phone. However, an administrator can configure this behavior for a user by accessing the Directory Number Configuration page if the user for some reason does not have access to the CFwdAll softkey.
The Forward No Answer External setting forwards any calls from the PSTN that go unanswered by the user. Similarly, the Forward No Answer Internal setting forwards any internal calls that go unanswered by the user.
