About Auto ID

The Auto ID feature alerts a hearing person that you are calling
from a TTY. It alerts the person by sending several audible tones
over the telephone line every few seconds. Auto ID helps emergency
services such as 911 detect that you are calling by TTY.
Auto ID comes on when you turn on your Supercom 4400 and
continues until you start a conversation. If you are on-line, you will
see SENDING AUTO ID on the display every time the Supercom
4400 sends out tones.
Auto ID will also begin sending characters whenever no one types
for a few minutes during a conversation. It will continue until
someone starts typing.
Auto ID is not the same as Caller ID, which is a separate service available
through your telephone service provider.
