We briefly review our recent works where we use dispersion rela- tions to constrain fits to data on πK → πK and ππ → KK providing a simple but consistent description of these processes. Then, simple analytic methods allow to extract parameters of poles associated to light strange resonances without assuming a particular model. We also present preliminary results on a model-independent determination of the controversial κ or K0∗(700) resonance parameters, by using those constrained parameterizations as input for partial- wave hyperbolic dispersion relations that allow to perform a rigorous analytic continuation to determine its associated pole.
