Feature Request - Beep on DSSkey attendant transfer

[bazzacad]

When our receptionist transfers a call to someone with the DSSkey attendant transfer button, there is no beep when or indication when the call has actually been transferred. She might say something like "here's the call" but we don't know if it takes 1 sec. or 5 sec. for her to hit the transfers button. So there's an awkward silence when the transfers happens, they "Hello, Hello, are you there"...

Please add a beep when an attendant transfers takes place.
