Abstract
A system and method for a caller to control a tune notification for a telephone call includes a service switching point and a service control point. The service switching point is operable to receive a tune notification service access code and a called directory number, and to issue a query in response to receiving the service access code. The service control point is operable to receive the query and issue a response including a tune notification signal to the service switching point. Upon receiving the response from the service control point, the service switching point processes the call so that the tune notification signal causes the tune notification to be applied to a called telephone line associated with the called directory number.
