We have developed a new X-ray absorption model, called {\tt IONeq}, whichcomputes the optical depth $\tau(E)$ simultaneously for ions of all abundantelements, assuming ionization equilibrium and taking into account turbulentbroadening. We use this model to analyze the interstellar medium (ISM)absorption features in the Milky Way for a sample of 18 galactic (LMXBs) and 42extragalactic sources (mainly Blazars). The absorbing ISM was modeled as acombination of three components/phases - neutral ($T\lesssim1\times10^{4}$ K),warm ($T\sim5\times 10^{4}$ K) and hot ($T\sim2\times10^{6}$ K). We found thatthe spatial distribution of both, neutral and warm components, are difficult todescribe using smooth profiles due to nonuniform distribution of the columndensities over the sky. For the hot phase we used a combination of a flatteneddisk and a halo, finding comparable column densities for both spatialcomponents, in the order of $\sim 6-7\times10^{18}\;{\rm cm^{-2}}$, althoughthis conclusion depends on the adopted parametrization. If the halo componenthas sub-solar abundance $Z$, then the column density has be scaled up by afactor $\frac{Z_\odot}{Z}$. The vertically integrated column densities of thedisk components suggests the following mass fractions for these three ISMphases in the Galactic disk: neutral $\sim~89\%$, warm $\sim 8\%$ and hot $\sim3\%$ components, respectively. The constraints on the radial distribution ofthe halo component of the hot component are weak.
