Abstract: The present disclosure provides a method for filtering an incoming call to a communication device. The communication device stores a default ring duration M and a default call frequency N. The communication device may calculate the ring duration of an incoming call, and further determines whether the ring duration reaches the default ring duration M. If the ring duration does not reach the default ring duration M, the communication device determines whether a call frequency of the incoming call reaches the default call frequency N. If the call frequency reaches the default call frequency N, the communication device blocks a phone number of the incoming call.

Abstract: An electronic device sets an identifier for each contact stored in a phone book, automatically creates a short message which contains the identifier according to a preset message template, and sends the short message to a phone number of the contact to inform the contact of the identifier. In response to receiving a call from a contact, the device prompts the contact to input an identifier, and detects if one or more push-button signals have been received from the contact by a dual-tone multi-frequency (DTMF) decoder. If no push-button signal has been received, the device determines the contact fails validation. Otherwise, the DTMF decoder decodes the received one or more push-button signals to determine data information input by the contact, and then the device determines if the contact passes the validation by determining the data information matches an identifier of the contact that is stored in the phone book.
