Abstract
Allowing the setting and resetting of a message waiting indicator on a wireless set when a message is waiting in a messaging system. When a messaging system receives a message for a wired set, it places a telephone call to the wireless set associated with the wired telephone set. The messaging system will continue to place telephone calls to the wireless set after every elapse of a predefined period. The wireless set is connected to a wireless switching system which is responsive to telephone calls from the messaging system to set a message waiting indicator. If a telephone call is not received within the predefined period from the messaging system, the wireless switching system resets the message waiting indicator. In another embodiment, the messaging system is responsive to a user accessing messages stored for that user to place a telephone call to a second telephone number identified with the wireless set of the user. The wireless switching system is responsive to telephone calls to the second telephone number of the wireless set to reset the message waiting indicator on the wireless set.
