  In this paper we derive new static phantom traversable wormholes by assuming
a shape function with a quadratic dependence on the radial coordinate r. We
mainly focus our study on wormholes sustained by exotic matter with positive
energy density (as seen by any static observer) and a variable equation of
state $p_r/\rho<-1$, dubbed phantom matter. Among phantom wormhole spacetimes
extending to infinity, we show that a quadratic shape function allows us to
construct static spacetimes of finite size, composed by a phantom wormhole
connected to an anisotropic spherically symmetric distribution of dark energy.
The wormhole part of the full spacetime does not fulfill the dominant energy
condition, while the dark energy part does.
