A dynamic model comprising anisotropic viscoelastic solid with voids along with two temperature and three phase lag is used to study the propagation of harmonic waves. The system of differential equation is made dimensionless by incorporating suitable quantities. Harmonic type plane wave solution is assumed to determine the Christoffel equation. From this equation five quasi-waves are noticed which vibrate with distinct speed in infinite medium and are under the impact of void, phase lag and viscosity. The velocity and attenuating factors of waves are computed numerically in three dimensional space. The influence of viscosity and void have been seen on the characteristic of waves. Different unique cases are also determined.
