What is acTrunkIndex?

Reports the trunk identifier on the switching board where a call is active, a read-only value from 0 to 83. Network operators use this to locate which physical trunk is handling a particular call for troubleshooting and load balancing. A trunk index of 5 identifies the sixth physical trunk on the board carrying that active connection.
