In Call Usage reporting in Variphy Insight, for each call record, the Cause Code fields can be used to determine whether the originating or the terminating/destination party hung up first.
The originating or calling party hung up first if the Originating Cause Code is “Normal call clearing”.
The terminating/destination/receiving or called party hung up first if the Terminating Cause Code is “Normal call clearing ” .
“Abandoned Calls” can also be identified, by where the call never connected (Call Duration = 0 secs) and the calling party hung up first.
