Page 24: Callback Request (Callback Queuing) 2 - 1
Callback Request (Callback Queuing) The Callback Request (Callback Queuing) feature provides System 25 users with a simple way to complete calls to busy facilities (stations or trunk groups), without having to manually repeat the calling procedures. This feature saves time for users because they can avoid repeated dialing of busy numbers.
Page 25 Callback Queuing Considerations for Inside Calls: If queuing tone is heard, the call has automatically been put into a queue. If busy tone is heard, callback can be requested manually. If special ringback tone is heard, callback can be requested manually. Off-Hook Queuing After a call has been queued, the caller can wait off-hook for the connection to be completed.
Page 26 To make an outside call, the user either dials the Automatic Route Selection (ARS) access code or the pooled facility, then after second dial tone, the rest of the desired outside number. If all trunks in the selected group are busy, and the calling station is administered for automatic queuing for outside calls, queuing tone is returned to the caller.
Page 27 Canceling a Callback Request Lift the handset and listen for dial tone. Press the button associated with the call. Press [DROP] Press the button associated with the call again. Hang up. Single-Line A single-line voice terminal can queue only one call at a time. Requesting Callback Press the switchhook.
Page 28 Call Waiting The Call Waiting feature allows a user at a busy voice terminal to be audibly alerted when another party is calling.

If the attendant hears special ringback, it indicates the voice terminal is busy but the called party has been notified of a waiting call.
Page 125 3-8 Attendant Features...
Page 126 C a m p - O n The attendant uses the Camp-On feature to extend a trunk call to a busy voice terminal and allow it to wait (“camp-on”) there. When the attendant camps-on a call, the called-party is notified by a burst of tone heard through the handset: one short tone for an inside call, two short tones for an outside call.
Page 127 3-10 Attendant Features...
Page 128 Cancel The Attendant Cancel feature allows the attendant to terminate an attempt to extend a call and return to the held calling party by pressing one button. If the called party is busy, does not answer, or if the station answers but declines to accept the call, the attendant presses the CANCEL button to return to the calling party.

Page 130 Conferencing An attendant can set up a conference that includes System 25 stations as well as outside callers. A conference call can have a maximum of five conferees; however, no more than two of the conferees may be on outside lines. The basic technique for setting up a conference is to start with an established call, then contact the new parties, one at a time, and add them to the conference.
Page 131 Dropping a Conferee When you drop a conferee, anyone added to the conference by the dropped conferee is also dropped. In addition, if you try to drop the person who added you to the conference, you will drop the entire conference. 1 Press [DROP] 2 Press the button of the conferee you want to drop.
Page 132 Typical Displays: Each time a party is called for a conference, the normal information is displayed. Call to an inside station: Asay,J Call to an outside station: 95551634 As each new party is added to the original loop, the display shows the number of conferees (including you) now connected together, along with the current number of calls waiting in the queue.
Page 133 3-16 Attendant Features...
Page 134 A DTAC attendant does not have the option of remaining connected to an extended call. If the attendant extends a call from outside System 25 to a busy voice terminal, the caller will be placed on hold and the called party will hear a tone that indicates they have a waiting (camped-on) call.

Page 158 Position Busy An attendant can use POS BUSY to send most calls that come to the attendant console to the other attendant, or (SLAC only) to a designated “backup” station. Only one attendant console can be placed in Position Busy mode at a time. DTAC For DTAC systems, POS BUSY can only be used when there are two attendant consoles.
Page 159 S L A C To use Position Busy, a system with a SLAC(s) must have either two attendant positions or one position and a multiline voice terminal administered as a “backup.” If the system has two consoles, pressing POS BUSY on one console will make it inactive and cause most calls in the common queue to be directed to the active console.
Page 160 Release Release is used when the attendant extends calls. It releases the attendant from the connection to the calling and called parties and completes the call transfer. There are two types of Release: Manual and Automatic. Manual Release: The attendant presses RELEASE to invoke the feature. Automatic Release: Simplifies the attendant procedures by eliminating the need for pressing RELEASE while extending calls.
Page 161 3-44 Attendant Features...
Page 162 Return Coverage on Busy Return Coverage on Busy returns to the attendant, after a specified time period, an unanswered camped-on call. If Attendant Camp-On is not provided (that is, Camp-On return time is administered to be zero seconds), calls released by the attendant to busy voice terminals return to the console immediately.
Page 163 3-46 Attendant Features...
Page 164 Return Coverage on Don't Answer Attendant Return Coverage on Don't Answer allows unanswered calls extended by the attendant to be returned to the attendant for additional service. Calls that are not answered after a specified number of rings return to the RTN-DA buton on the DTAC, or to a LOOP button on the SLAC.
