Matrix: How do I remotely hang up a telephone line from an ECS 5.2.2 ICS-2003 panel?

Question:  How do I remotely hang up an incoming telephone call from an ECS 5.2.2 equipped ICS-2003 panel?
Answer:  This function is available only if specifically enabled in the configuration program. Go To ECS 5.2.2 > Cards and Ports screen and enable "REMOTE LINE RELEASE" in panel options for the specific panel to be enabled.  
To hang up a TEL-14 telephone interface left off the hook:
1. Push and hold the “Listen Level” button on the ICS-2003.
2. The CALL SIGNAL message should be displayed on the ICS-2003 display
3. Wait for approximately 2 seconds after the CALL SIGNAL  message appears on the display.
4. While holding the “Listen Level” button, press the talk selector for the desired telephone interface.
5. Release the “Listen Level” button.
Note: In addition to hanging up the telephone interface, this will deactivate any talk/listen selector set to the interface from anywhere in the system.
