While Unity is playing a call handler greeting, if the caller inputs a value that Unity does nto understand, Unity plays the Default Opening greeting.
How do I disable this behavior? I vaguely remember that this could be done in the Advance Setting Tool but I don't recall the option.
This is from Unity Design Engineer Jeff Lindborg;
"You can expose the error greeting in the SA interface using the Advanced Settings tool. You can also use BulkEdit to do the for all your handlers and subscribers if you like - there's a special option called "loop back to self" for the error greeting option that's made just for this type of thing." Jeff
Hope this helps!
