Parameters
threshold: Silence threshold value in the range of 0 to 200. If the amplitude of voice signals from the
switch is smaller than this value, the system regards the voice signals as silence. Generally, the signal
amplitude on the links without traffic is in the range of 2 to 5.
time-length: Silence duration for automatic on-hook, in the range of 2 to 7200 seconds. Upon expiration
of this duration, the system performs on-hook automatically.
