We report on progress applying the stochastic LapH method to estimate all-to-all propagators required in correlation functions of multi-hadron operators relevant for pion-pion scattering. Large-volume results for I=2 and I=1 pion-pion scattering phase shifts with good statistical precision are obtained from an N\rm f = 2+1 anisotropic Wilson clover ensemble with mπ = 240MeV. We also present a preliminary determination of the I=1 pion-pion scattering phase shift and timelike pion form factor on an isotropic N\rm f=2+1 flavour ensemble generated by the Coordinated Lattice Simulation (CLS) community effort.
