Yes, you do gain another Attack Phase, so you can choose to attack with any not-rested cards as a normally would, which includes them not attacking, no matter with the amount called.

Technically, you can get another Attack Phase even if no other cards are called by its effect if you have an standing Weapon equipped, or if a standing monster is protected for some reason from the destruction effect, like Soul Guard or a protection card.
