  We study the time evolution of the test scalar and electromagnetic fields
perturbations in configurations of phantom wormholes surrounded by dark energy
with state parameter $\omega< -1$. We observe obvious signals of echoes
reflecting wormholes properties and disclose the physical reasons behind such
phenomena. In particular, we find that the dark energy equation of state has a
clear imprint in echoes in wave perturbations. When $\omega$ approaches the
phantom divide $\omega=-1$ from below, the delay time of echoes becomes longer.
The echo of gravitational wave is likely to be detected in the near future, the
signature of the dark energy equation of state in the echo spectrum can serve
as a local measurement of the dark energy.
