Issue:
My TNG reports list partially dialed numbers and short calls. This clutters my reports.
Solution:
TNG has a "Call Filter" facility to discard calls shorter than the configured duration. The Duration can be configured per call type.
Access this facility through the "Settings" screen and scroll down to "Minimum Call Duration (seconds)". Add the values that you would like to use and Apply your settings. Calls shorter than these configured values will now be discarded.
