What did Odysseus do to escape from Scylla and Charybdis

Before Odysseus and his men depart, Circe told Odysseus that he must pass the island of the Sirens, who will try to lure the men to their deaths with their songs ... Odysseus asked if he can escape Charybdis and fight off Scylla, but Circe chastised Odysseus for his stubbornness: Scylla is immortal and can't be defeated.
