Calls that are dropped while navigating an IVR will show in the To-do section of the app for any agent associated with the IVR number, regardless of caller selection. The missed call will be attributed to the IVR number, not to the leg of the IVR where the caller disconnected the call.
If a caller never hits a Ring To widget, they will remain "in" the IVR. Any actions done while "in" the IVR will show for all agents associated with the IVR number.
As an example, you have an IVR where option 1 rings to Team 1 and option 2 rings to Team 2. An inbound caller selects 3 (or does not make a selection at all), and it routes the call to the No or Wrong Input Leg. This will result in the caller never leaving the IVR, so whether the caller leaves a voicemail or hangs up, the agents in Team 1 and Team 2 will all be notified of the missed call.
Please note, if the caller selects 1 and the call starts ringing to Team 1 and then the caller hangs up, the agents on Team 2 will be notified of a missed call as the agents from both teams are associated with the IVR.
The easiest way to prevent this notification from occurring is to have each selection go to a separate number which then rings the team. This way, if a call is disconnected while ringing Team 1's number, Team 2 agents will never be notified of a missed call as they are not associated with that number.
