What does target disconnected mean in Interaction Records?

I’m trying to determine if a call was disconnected by our Agent, or by our Customer - looking through Interaction Steps, the Connect Call block exit says “TargetDisconnected”. Does that mean the caller hung-up?

“Target Disconnected” in the interaction record is the indicator that the Agent hung up, before the Caller.

Another way to view this is to review the Call Detail Report

The system disposition (see attached) will show Callee Terminated - this means that the target party (The agent, in this case) hung up first
