  • Patent number: 7218614
    Abstract: A method and apparatus for notifying a user device coupled to an integrated services hub (ISH) that a remote device has terminated communication with the user device. A network interface within the ISH receives a disconnect message from the remote device and routes the disconnect message to a CPU. The CPU determines which user device had been in communication with the remote device and sends a call termination notification signal to a user device interface coupled to the appropriate user device. The termination notification signal comprises temporarily placing the user device interface in a disabled state for a predetermined amount of time. After sending the call termination notification signal, the CPU detects whether the user device is still in an off-hook status. If the user device is off hook, the CPU sends another call termination notification signal by again temporarily placing the user device interface in a disabled state.
