1.2 Making Calls

• You can lock message waiting indications so that other extensions cannot confirm, call back, or clear message waiting indications left at your extension (Message Waiting for Another Extension Lock). The operator or manager can cancel this feature for all extensions (Extension Lock—CANCEL ALL). Even while this lock is on, you can confirm, call back, or clear message waiting indications left at your own extension.

On your proprietary telephone (PT), you can establish one or more Message for another extension buttons. These buttons can display message waiting indications left at other telephones.

To cancel all message waiting indications left at another extension, it is necessary to first assign the corresponding Message for another extension buttons on your phone.

The MESSAGE/Message for another extension button light or Message/Ringer Lamp shows the current status as follows: 

Off: No messages 

Red on: New messages.

The display shows messages in the order received, starting with the selected message. Example!

5ο6ο7ο8ο1ο2ο3ο4

The MESSAGE button is used to perform operations and display notifications from both the Message Waiting and Built-in Voice Message (BV) features. If a message has also been left in a voice message area, "Voice Message" will be shown on a display PT when the MESSAGE button is pressed. Refer to "1.5.5 Using Voice Messaging (Built-in Voice Message [BV])".

Each extension can have a maximum of 8 messages waiting when using the Message Waiting feature, or a maximum of 125 voice messages waiting when using the BV feature.

If you go off-hook with a single line telephone (SLT) that has messages waiting, a special dial tone (dial tone 3) will be heard. You can call a caller back or listen to the message by entering the Message Waiting Answer feature number, "784# (7840)".
