# Modify A Mailbox by Phone

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:

1. Access the Telephone Administration Menu.

2. Press the M (the 6 button) to modify a mailbox.

3. 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.

4. Press X (the 9 button) to exit the Administration Menu.
