Integration over polytop

I would like to integrate function over domain defined by inequalities

Actually, I use the function Boole[]:
NIntegrate[f[x,y,z,t]Boole[ineq],{x,-Infinity,Infinity},{y,-Infinity,Infinity},{z,-Infinity,Infinity},{t,-Infinity,Infinity}]

But this is too slowly and the result don't have a good precision.

How can I do to integrate, functions that depend of many (3,4,...10) variables
over domain define by inequalities (linear or quadratic)?

Thancks
