# Overview

A special feature of this system allows you to perform various administrative functions from a telephone. The Administration by Phone feature is convenient when the system's maintenance console is located at a distance from the workstation.

Although this feature cannot completely replace console administration, telephone administration software supports numerous features available from the console, and is appropriate for specific functions discussed in this section.

Note: If your system has more than one line group and more than one administrator’s mailbox, you must ensure that you call the line group associated with the administrator’s mailbox that you are using in order to conduct Administration by Phone.

Administration by Phone is not available to mailboxes with the NP TDD line group configuration.

## Telephone Administration Timing

Certain timing parameters are programmed into Administration by Phone to detect inactivity and to safeguard the system against unauthorized use. These time-out factors make it essential for you to be well-prepared before you begin a telephone administration session.

- Three to five seconds of response time are permitted for each prompt before it announces “no change” and returns to the Administration Menu.

- Any activity causes a one-minute timer to start, after the system accesses administration. If one minute lapses without input, the system automatically disconnects, and the entire access procedure must be repeated.

- If you are running out of time, enter the digit 1 (one) in response to any prompt, to restart the timer. The system issues an error message and repeats the prompt.
