Using clipping diodes for limiting dialling pulses in the receiver is a bit of a 'sticking-plaster' solution. If you are hearing loud clicks when dialling, then your 'dial-off normal' contacts need cleaning! These contacts are configured to shunt the receiver and/or to quench any sparks produced by the dial contacts, giving rise to induced clicks.
Deal with these issues first before slapping in a couple of diodes.
