Yesh, I was referring to that if It would have been in the cellar, that could only happen if It breaks one of the waterpipes open to exit. And that would not go unnoticed, especially by Zack, who actually works at the Water Company of Derry. Even though It could teleport itself to limited distances, there is proof that It can not teleport thru solid materials, i. e. a brickwall. So the chances for It being down the cellar is pretty slim. When It decided to enter someone's house, then scored a kill as well (the case of Frederick Cowan).
Apart from breaking a pipe open, I have no idea how It could sneak out of it unnoticed. Even in the movie, when It attacked Belch and Henry, the pipe ruptured open, and Belch was pulled inside.
The scene when It was talking from the radio using the voice of Georgie is after the death of Henry and before the adult Losers enter the Barrens. Guess It wanted to mock Bill and send this as an appetizer to thrill him.
