6.00 Automatic Callback
6.01 Automatic Callback-Trunk
Description
If no idle CO line is available when dialing a
feature number for selecting a CO line and the
telephone number of an outside party, the caller
hears special busy tone.
On-hook while hearing the special busy tone
calls back the caller as soon as a CO line
becomes idle: call-back ringing. Off-hook or
pressing the SP-PHONE button catches the CO
line automatically, and sends the last dialed
telephone number to the CO line.
Off-hook prior to the start of callback ringing
cancels this function.
Also no answer in four ringings (within 10
seconds) after the start of callback ringing
cancels this function.
To activate “Automatic Callback-Trunk,” assign
“Extension-Station”, Automatic Callback-Trunk to
“Yes.”
This setting is assignable on an extension basis.
Programming
Conditions
Multiple extensions are able to set this function to
one or more CO lines at the same time.
A maximum of 64 Automatic Callback-Trunk can
be active in the system.
If 64 extensions already set this function to one
or more CO lines, another caller's attempt to
execute this setting is rejected by normal busy
tone, not by special busy tone.
Even if an extension user sets Call Forwarding-
No Answer or Do Not Disturb, he or she can set
Automatic Callback-Trunk: callback ringing is
effective to the extension.
Automatic Callback-Trunk cannot be set by the
extension which has a consultation hold call.
