A generalized Anderson model for a magnetic ion in a harmonic potential is formulated. The model is investigated by the numerical renormalization group (NRG) method. In addition to the conventional $s$-wave screening, the model exhibits phonon assisted $ p$-wave Kondo effect as well as Yu and Anderson type Kondo effect. It is shown that the $s$-wave Kondo and the Yu-Anderson Kondo belong to the same fixed point. At the boundary between the $s$-wave and $ p$-wave Kondo regions line of fixed points of the two channel Kondo effect is identified.
