TNG will not apply cost/charge for calls in the following instances:
- Duration of the call is 0
- The call has an action of "Unanswered"
- The ratebook that was selected is "Do_not_Cost"
- The Number that was dialed, can't be found in the Ratebook that is configured for the Trunk
- Call ACTION or TRUNK has a value of: INTERNAL, VOIP-INT, INCOMING, VOIP-EXT
If none of the above criteria matches the call, the call will be costed.
NOTE: For calls to match the criteria, the PABX must give off the standard output format and the latest version of the plugin must be used.
There are cases where calls might be costed "incorrectly", based on the information that was given to TNG:
- Situation 1:If the PABX identifies a call as 'unanswered' and there is a short duration, there will be a cost.
Solution 1: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.
