Method for notifying a wireless unit that a wireline unit is in an off-hook state

摘要

The present invention provides a method for notifying a wireless unit that a wireline unit is in an off-hook state. A central office switch determines that a wireline phone is in an off-hook state. The central office switch determines if the receiver off-hook monitoring feature is active for the wireline phone. If so, the communication system sends a message to a wireless unit associated with the wireline phone to alert a user of the wireless unit that the wireline unit is off-hook. When the wireline unit goes back on-hook, the communication system sends an on-hook message to the wireless unit to indicate that the wireline phone has returned to the on-hook state.
