"She seems to have calmed down now. She's speaking," a male caller told the operator.
Moore announced in November that she had decided to end her marriage to Ashton Kutcher following news of alleged infidelity.
Moore, 49, and Kutcher, 33, were wed in September 2005.
Kutcher became a stepfather to Moore's three daughters — Rumer, Scout and Tallulah Belle — from her 13-year marriage to actor Bruce Willis. Moore and Willis divorced in 2000 but remained friendly. Moore and Kutcher were photographed socializing with Willis, and the couple attended Willis' wedding to model-actress Emma Heming in 2009.
Moore and Kutcher created the DNA Foundation, also known as the Demi and Ashton Foundation, in 2010 to combat the organized sexual exploitation of girls around the globe. They later lent their support to the United Nations' efforts to fight human trafficking, a scourge the international organization estimates affects about 2.5 million people worldwide.
Moore can be seen on screen in the recent films "Margin Call" and "Another Happy Day." Kutcher replaced Charlie Sheen on TV's "Two and a Half Men" and is part of the ensemble film "New Year's Eve."
