AT&T Voice DNA Feature  Procedure 
Auto Call Back Busy 
If you call a phone number that's busy, Auto 
Call Back Busy checks the busy number for the 
next 30 minutes. When the phone number 
becomes free, Auto Call Back Busy rings you 
and then connects the call. If you change your 
mind, you can cancel Auto Call Back Busy at 
any time. Note that you can have multiple 
Auto Call Back Busy sessions running at the 
same time. 
Note: If you place a call to a number that has 
voicemail, you'll be sent to voicemail and Auto 
Call Back Busy won't check the number. 
Turn on Auto Call Back Busy: 
1.  Make your call. When a number is busy, a voice 
prompt offers Auto Call Back Busy. 
2.  Follow the voice instructions. The voice prompt 
then confirms that Auto Call Back Busy is turned 
on. 
3.  Hang up. 
4.  When the number you called becomes free, your 
phone rings. Answer the call to connect to the 
number you originally called. 
Cancel all Auto Call back Busy sessions: 
•  Enter *86 and then press the Dial soft key. 
Call Waiting 
If you see a new caller's ID in your phone's 
display window while you are on a call, Call 
Waiting is turned on, and you have an 
incoming call. 
If you don't answer the new call, it will be 
routed to your voicemail (if available) or to 
your chosen "when I don't answer" call 
treatment. 
If you don't want to be notified when callers 
are waiting, you can turn Call Waiting off for 
the current call. 
Turn Call Waiting off for the current call: 
1.  Enter *70 and the number you want to call. 
2.  Press the Dial soft key.
