ABSTRACT:
A periodic and automatic telephone redialling system and method applicable to a dial-type communication device is proposed to provide a periodic and automatic telephone redialling procedure on phone numbers previously dialled by a user but failed to get through to the receiver. The advantages of this periodic and automatic telephone redialling system and method are that the user does not have to activate the redialling procedure manually, and the redialling procedure can be performed periodically for one or more phone numbers.
