Automatic Callback; Automatic Callback-Trunk - Panasonic KX-T336 System Reference Manual

4.00 Automatic Callback
4.01 Automatic Callback-Trunk
Description
When no idle CO line is available after dialing a
feature number for selecting a CO line and the
telephone number of an outside party, the caller
hears special busy tone, if this feature is
assigned.
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
catches the CO line automatically, and sends the
.3
last dialed telephone number to the CO line.
Off-hook prior to the start of callback ringing
cancels this feature.
Also no answer in four ringing tones (within 10
seconds) after the start of callback ringing
cancels this feature.
To execute this feature, assign "Extension-
Station", Automatic Callback-Trunk to "Yes" on an
. extension user basis.
