Feature description

Automatic Redial (ARDL) extends the redialing capabilities of the Ring
Again and Network Ring Again features. The redialing capabilities of this
feature reside at the system level. The system generates redialing attempts
that allow the calling party to redial a busy public network subscriber using
analog or digital trunks.

This feature is applicable when a calling party dials a public network
subscriber number and receives a busy indication. Instead of attempting
repeated redial efforts, the calling party can activate ARDL by pressing
the Ring Again (RGA) key.

Once activated, the ARDL feature requests the system to automatically
redial the attempted dialed number until a successful call termination is
completed or until the configured number of redial attempts is reached. A
successful call termination is determined when one of the following occurs:
a tone detector attached to the call detects a ringback tone, an answer
signal is received or an ISDN signaling trunk indicates call termination.
