AUTOMATIC CALL BACK

 (On-campus calls only) 

Automatic Call Back (ACB) feature allows a user calling a station that is busy, or 
does not answer, to request a callback when the station becomes free.   (The 
user may make and/or receive calls while the Automatic Call Back feature is in 
effect.) When the station marked for call back becomes available, the system will 
ring the user’s extension with eight seconds of fast ringing.  Lifting the handset 
will place a call to the extension marked for Automatic Call Back. (The user must 
pick up the handset before the ringing stops, or the call back will be canceled.)  
Several Automatic Call Backs can be activated at the same time.  An Automatic 
Call Back cannot be initiated to an off-campus number. 

To request an automatic call back
