We study regular and asymptotically flat phantom black holes as gravitational
lenses. We obtain the deflection angle in both the weak and the strong
deflection limits, from which we calculate the positions, magnifications, and
time delays of the images. We compare our results with those corresponding to
the Schwarzschild solution and to the vacuum Brans-Dicke black hole.Comment: 14 pages, 4 figures; v2: improved and extended version, new
