We have an app where in a user needs to queue for a call with a consultant. Their queue number goes up each time the consultant finishes a session. E.g. From queue no. 3, it will become 2, and then 1.
What is the best way to alert the user that it's already their turn? I am thinking to have 1 'ding' sound each time the queue no. changes, and when it's the user's turn, will have another sound (longer sound, maybe like a ding-ding-ding).
The only problem is if they turn their sound off. Then there's no use for the sounds.
Is there any other way to do this?
