This has been going on and on since version 2 I guess. The busy tone is enabled in the Sounds settings. But when my call to someone is rejected, I see the word "Busy" but I do not hear the Busy tone. Only the Hang Up tone is heard.
I understand that this is another small issue I have reported. But what's the point of having a busy sound when its not used?
So is anyone going to fix this in the upcoming 2.6?
