  In the framework of the dispersion relation N/D-method we restore the
low-energy pi-pi (IJ^{PC}=00^{++})-wave amplitude sewing it with the previously
obtained K-matrix solution for the region 450--1900 MeV [V.V. Anisovich, Yu.D.
Prokoshkin and A.V. Sarantsev, Phys. Lett. B389, 388 (1996)]. The restored
N/D-amplitude has a pole on the second sheet of the complex-s plane, near the
pi-pi threshold. We discuss the hypothesis that this low-mass pole, or the
low-mass sigma-meson, corresponds to the dynamical state related to the
confinement forces, that is the eyewitness of confinement.
