The spectrum and damping of collective excitations of a system of electric dipole centers with internal degrees of freedom in glass are calculated. It is shown that one of the collective modes becomes soft, signaling a spin-glass like phase transition in insulating glass. The contribution to the specific heat is determined. The possibility of phase transition from paraelectric to electric pseudospin glass phase in dielectric glass is considered.
