A mechanism is provided for detecting when a wireless device is entering a quiet zone. An out-of-range condition is created in an entryway to a quiet zone. When a wireless device is in a transition zone, the device transmits a re-scan message with a unit identification in an attempt to reestablish communication with the communication tower. A re-scan receiver is provided in the entryway to receive re-scan messages and notify a mobile telephone switching office that the device is entering a quiet zone. The switching office then sends a ring type modifier property to the device when the device leaves the transition zone and reestablishes communications with the communication tower.
