Systems and method for call waiting suppression are disclosed. When a communications device is engaged in an active communication and receives an incoming communication, a call waiting alert is activated to produce a single, initial audible alert, and thereafter the subsequent call waiting alert(s) are silenced according to a call waiting suppression profile. Alteratively, an audible indicator of the call waiting alert may be deactivated for the incoming communication, while other indicators remain active to alert the receiving party of the incoming communication.
