    We study the solvability of the inverse problems on finding a solution $u(x,t)$ and an an unknown coefficient $c$ for a telegraph equation $$u_{tt}-\Delta u +cu=f(x,t).$$ We prove the theorems of the existence of the regular solutions. The feature of the problems is a presence the new overdetermination conditions for the considered class equations.
