By default, what are two options that are presented to callers for directed calls into a Cisco Unity Connection system? (Choose two.)

When a call is directed to a specific subscriber's mailbox, Cisco Unity Connection by default allows that subscriber to log in by pressing the sign-in key and entering only their PIN, because the system already knows which mailbox was targeted.

The opening greeting is played for calls arriving at the general pilot number, not as a presented option during a directed call to a specific subscriber's mailbox.

Leaving a message for the forwarded subscriber is the implicit default action of a directed call rather than an explicitly presented menu option alongside the login prompts.

Any other caller who wants to access their own mailbox can also press the sign-in key and will be prompted to enter both a user ID and PIN, since the system does not know their identity from the directed call alone.

Logging in to a remote mailbox via a remote networking link is not a default option presented to callers on directed incoming calls.
