Send Polarity Reversal
If polarity reversal is enabled, call tolls will be calculated based on
the changes in voltage. If polarity reverse is disabled, you need to
set the time for offhook detection and call tolls will be calculated
starting from the set time.

and a maximum time. If a phone’s hook flash is pressed for a time

If a phone’s hook flash is pressed for more the set maximum time,
the action is considered as ‘hang up the phone’.
