Beyond animation, a significant portion of her dubbing work has been for live-action television, particularly soap operas and telenovelas. She dubbed characters in numerous popular series, including Priscilla Presley and Morgan Fairchild's roles in Dallas, Nancy Lee Grahn in Santa Barbara, Demi Moore and Robyn Bernard in General Hospital, and Tonya Lee Williams in Febbre d'amore (The Young and the Restless). Her voice can also be heard in Italian adaptations of primetime series such as Roseanne Barr in Pappa e ciccia (Roseanne), Sela Ward in Sisters, and Monica Bellucci in Vita coi figli.

Later in her career, Sestito expanded her role in the dubbing industry to include dialogue adaptation and dubbing direction. She was responsible for adapting the Italian scripts for telefilms like Pappa e Ciccia, Friday Night Lights, Modern Family, and Parks and Recreation. From 2011 to 2012, she also served as the dubbing director for the soap opera La strada per la felicità.
