We consider O(N,1) noncompact sigma models quantized in an indefinite-metric space. In two dimensions, by direct computation we prove the existence of a positive-metric subspace where the S matrix is unitary. The properties of the model as a function of the temperature are investigated in various space-time dimensions.
