Timeouts
DTMF 1st Digit
How long to generate dial tone in milliseconds before the 1st digit of the phone number is
pressed on the phone. If this time expires it is likely the phone has been left off the hook
accidentally and a special rising tone at maximum volume is made to prompt the user to
hang-up.
DTMF Digit
How long to wait for another phone digit before we assume the number has been fully
entered. Trade off between being too quick for a slow dialler to extending the time taken to
place a call unacceptably.
Call Termination
How long to wait in minutes with nothing heard before we hang-up a terminal initiated call
assuming it has been left in a call accidentally. Set to 0 to disable this feature and leave a
call up forever. The next two parameters can fine-tune what ‘nothing heard’ means, allowing
the sensitivity and impulse immunity to be adjusted.
