## Message Facility

## Definition

Message Facility means that internal and external callers can leave messages in ASB 150 02.

A flashing lamp on system telephones indicates that a message is waiting.

On extensions with analogue telephones message waiting is indicated by a special dial tone that the user hears when he lifts the handset.

## Use

Messages can be left when one wishes to contact someone who does not answer or, for example, if one wants to send information to one or more extensions in the system.

## Operation

### Message facility with a VMU-D board

#### STANDARD-, ECONOMYplus- and BASIC telephone

A message is signalled by the lamp adjacent to the message waiting key lighting and then flashing rapidly. The message is answered by lifting the handset and pressing the key.

If the message is a “call-me” message, a call will be made to the extension/service quarter that has left the message.

The guest receives the ring control tone.

If the message is a voice message, the guest receives a short tone followed by the recorded message.

The message is repeated twice.

#### Analogue telephone

A message is signalled by the lamp adjacent to the message waiting key by lighting and then flashing rapidly. The message is answered by lifting the handset and dialing *59#.

The rest of the procedure is the same as for STANDARD-, ECONOMYplus and BASIC telephones.

### Message facility with a VMU-HD/MFU board

You can assign each extension to a MAILBOX. This means that an extension has the opportunity to make a diversion to a mailbox.

In that case calls to the extension are diverted to the message system, where the caller can leave a voice message to the extension.

For more information, see Mailbox System (340/155 34-ASB 150 02 Uen).

## Capacity

There is no limit to the number of messages that an extension can send or receive.

The total number of messages in the system can amount to a maximum of 1000.

The number of voice messages is also limited by the available capacity on the VMU-D/VMU-HD/MFU board.

Stored messages are protected in the event of power failure.

## Limitations

Capacity of speech channels:

VMU-D/VMU-HD |  | 8 or 16 MFU |  | 4 |

The function “retrieving messages” has a lower priority than the voice announcements to the external caller. To prevent that too many channels are blocked simultaneously by the retrieving function, it is possible to restrict the access to all channels.

If no voice channels are free for internal retrieving, the following message is shown on the display (if any) of the caller: “CONGESTION TRY LATER”.

If no voice channels are free, external retriever or telephone sets without a display will receive ringing tone until a voice channel is free again.

If there is no free voice channel within timeout, the external caller will be rerouted to the reroute position of the relevant trunk.
