Disconnect Timing (msec)
This field specifies the minimum time in milliseconds that the central office or far-end media server or
switch requires to recognize that your end has disconnected from a call. This timer does not affect ports
on a circuit pack that uses the administrable Incoming Disconnect and Outgoing Disconnect timers; in
fact, settings on those two timers override this field.
Valid entries
140 to 2550 ms

Usage
The default of 500 is an industry standard and you shouldn't change
it. If you set this field too high, your server/switch won't disconnect
sometimes when it should; too low, and it will disconnect when it
shouldn't.
Usage
Usage
Select one. For security reasons, it's better to apply a tone: silence
could provide an opening for hackers.
Drop Treatment field must be administered as intercept for all DID trunk
