66 CHAPTER 5: STANDARD FEATURES
Using Automatic
Callback
Automatic Callback allows you to request a call back ring from a
destination extension that is in use or unanswered. The NBX system
attempts to connect you when the called party at that extension becomes
available.
On an NBX telephone, the Automatic Callback feature is helpful when:
■ The person you are calling is on another call and you want the system
to generate a call back ring as soon as this person is available.
■ The person you are calling does not answer the call and you want the
system to generate a call back when this person is available.
You initiate an Automatic Callback through Feature code 469 or a
programmed system access button depending on the type of NBX
telephone you have and how it is configured.
Initiating Automatic
Callback
You can initiate Automatic Callback while making a direct call to an
extension that is in use or unanswered.
On a 3Com Basic or Business Telephone or Attendant Console:
1 While on a call to an extension that is in use or unanswered, press
Feature + 469 (or press the Automatic Callback Access button if one is
programmed on your telephone).
2 Disconnect from the call.
■ If the Automatic Callback attempt is successful, the message
“Callback Extension XXX” appears on your display panel.
When the party on the destination extension becomes available, you
receive a call back ring. When you answer this call back, the
destination extension rings and your call then can be connected.
■ If the Automatic Callback attempt is not permitted, the message “Not
Allowed” appears on your display panel. See
“More About Automatic
Callback” in this chapter.
If the party on the Automatic Callback destination extension does not
return your call within the time set by the Automatic Callback Return
Interval, the system cancels the Automatic Callback request. For more
information, see the
“More About Automatic Callback” section.
