You should check the layer 3 messages during the call, see if there is any message sent or received when this drop occurs. It might (or not) give you an indication. (possible messages : channel release, disconnect…)
Also, check the QoS stats in the cell where you had the drop : what type of drops do you see at the hour of the drivetest ?
