Call Waiting

Call Waiting informs an ISDN BRI terminal user engaged in an active call that a call is waiting
to be answered. A call setup message is sent to a DSL when both B-channels are busy and
an incoming call is in progress. This causes a warning tone to the terminal speaker. To accept
the new call, the user must place the currently active call on hold or release the call.
Call Waiting is activated only if Hunting is not enabled or fails to handle the incoming call. The
incoming call may originate from an ISDN BRI or a non-ISDN BRI terminal.
Note:
The following test requires that the terminal receiving the second (call waiting) call has
multiple DN appearances. Otherwise, this test will fail.
