We see a lot of system disconnects in call detail report - what is it? who is dropping these calls?
Have a look at these calls in the interaction search. You can access the scenario steps and see exactly where a call disconnected and why.
Usually, these represent the calls that went back into IVR after connect call block, or calls that the system hung up on (e.g. after recording and confirming a voicemail).
You can add a set disposition block at key points to change what is reported or add additional functionality.
