The phone number or other identifying information of an incoming phone call or other network communication is optionally stored, and a call-back is optionally scheduled. The user is prompted whether to schedule a call back, and if so, a call-back sequence is initiated at an appropriate time. When a call-back sequence is initiated, the scheduled call-back number or address may be automatically dialed, or alternatively the user selects whether to go forward with the call-back routine, at which time the call-back continues if the user selects an affirmative response. As an option, the user can delay the call-back to a predetermined time in the future, or the call-back can be rescheduled or canceled. Associated notes or other text can be saved in a calendar along with the scheduled call-back event to remind the user the reason and subject matter of the call back. The invention provides integrated communications and calendaring features. The invention may be directed to telephony system such as cellular telephones or telephony enabled computers systems, or may be expanded to network communication such as e-mail or network addressing in lieu of telephony communications.
