Hi. Hate when you enable something and it doesn't work, you check the manual as it says "You can enable a Callback option – this allows callers to hang up and get called back when it’s their turn. This option requires that you specify an outbound rule on which the call back is to be triggered. The Call Back option can be requested by the caller (Option 2) or it can be offered if the timeout of the queue is reached." What are the details of the outbound rule? Does it use the normal outbound rule? Does it need to be called a certain name? Any Help?
