Abstract: The embodiments herein relate to call lists that detail all call attempts made to a called party that have not been successful in communication networks. The reasons for the failure can range from no answer to out of range or congestion in the network. A system and method is disclosed for notifying a called user of a failed call attempt made by a calling user. A switch receives a call request from a calling user and on determining that a communication session cannot be established between the calling user and the called user, the switch terminates the link to the calling user and sends the call attempt notification to the called user. The called user would be notified of the call attempt made by the calling user, the contact details of the calling user and reason for the failure of the call attempt.
