When Modify is selected from the Administration Menu, the system gives the current mailbox number, class of service, mailbox type, and an AC message waiting lamp address; then, it prompts for any changes. You can only perform this procedure from the administrator’s mailbox.
To modify a mailbox by phone:
Press the M (the 6 button) to modify a mailbox.
When prompted, enter the mailbox number to modify. The server responds with the current mailbox number, class of service, mailbox type, mailbox message waiting type, if applicable; then prompts you for changes. To leave any value unchanged, press the star (*) button in response to the prompt:
enter a new mailbox number, if required
enter a new Features class of service (FCOS).
enter a new Limits class of service (LCOS).
enter a 2-digit message waiting type
The server responds with "Mailbox modified," and returns you to the Administration Menu.
Press X (the 9 button) to exit the Administration Menu.
