Wait until free
The "Wait until free" feature is a "Callback if busy" feature without the sub-
scriber who initiates the call having to hang up. He stays on the phone and waits
until the busy subscriber becomes free. The callback is triggered as soon as the
called subscriber has been free for 5 seconds. The connection is then set up auto-
matically.
