Toshiba PERCEPTION 4000 - Manual (Page 65)

The system will process the call and attempt to access an outgoing
trunk. If your station is restricted from accessing any available trunks, you
will hear reorder tone.
If the least-costly routes are not available, a warning tone may sound to
indicate that higher-priced routes are being searched. At this point, you
can either hang up and call back when a lower-priced route is available,
or use an available higher-priced trunk.
NOTES:
1. A warning tone will not occur with emergency calls, calls made via a
hotline, calls made to an off-premises station, or calls that are
forwarded to an off-premises location.
2. In order for calls to be automatically routed over the least-costly call
facilities, your PERCEPTION 4000 system must be properly
programmed.
MESSAGE WAITING
When a dialed destination is busy or does not answer, you can leave a
message at the station through Callback Messaging so that the called
party can return your call. If your PERCEPTION 4000 system has a
connected voice mail system, you can also leave a message for a station
user by calling or being routed to the station’s voice mailbox. In each of
these cases, the called station will be informed of the waiting message
through stutter dial tone, a Message Waiting light indication, a Message
Waiting access key LED indication, and/or Message Waiting displays.
When a callback message is registered at your station, you can access
the message by simply accessing a line and pressing the Message
Waiting key. This will automatically call back the station that left the
message. If the message resides in your station's voice mailbox, you will
be automatically routed to the voice mail system when you press the
Message Waiting key. Once inside the voice mail system, you can access
the message by following voice mail operational procedures. After
accessing voice mail messages, you can return a callback message by
pressing the Message Waiting key again.
