2-376 Transfer
When a call is transferred to an extension programmed as a fax port, the call
is not returned to the originator and continues to ring at the fax extension.
This eliminates the possibility that the high-pitched fax tone would be heard
by a person who answers the transferred call.
If a multiline telephone user presses the Feature button after initiating a
transfer, the dialed digits activate a feature (for example, Privacy). After the
feature is activated, the user should redial the extension or telephone
number to transfer the call.
Calls cannot be transferred from a fax. However, inside and outside calls can
be transferred to an extension designated as a fax. Calls transferred to a fax
are not eligible for transfer return but the call remains on hold at the
originating station until the call is answered by the fax.
If the Transfer Return Interval (1-9 rings) is exceeded before a transfer is
completed, the call rings back at the telephone of the person who is
transferring the call.
Users can press inside Auto Dial buttons instead of dialing extension numbers
to transfer calls. To use the One-Touch Transfer option, users must program an
Auto Dial button for every extension to which they transfer calls. When a system
operator transfers a call and it returns unanswered, the green LED next to the
Auto Dial button flashes to indicate the extension from which the call is
returning. Only system operators receive this indication.
Automatic Line Selection does not work when the Transfer button is pressed.
A queued Callback call cannot be transferred, but calls transferred to busy
extensions are eligible for Callback. When a user reaches a busy extension
while transferring a call, automatic Callback or selective Callback can be used
to queue the call before completing the transfer. The caller hears ringback or
Music-On-Hold just like any ordinary transfer.
When the extension is available, the call is transferred to the extension
automatically. If the extension is not available before the Transfer Return Interval
expires, the call is removed from the Callback queue and returned to the
originator.
If a single-line telephone user with a call queued for a busy station completes a
transfer to a busy pool, the caller hears a fast busy tone. The transfer is
considered complete, and the call is not returned to the originator.
If a transfer is completed to a busy telephone, the destination hears the Call
Waiting tone, if programmed, and the caller hears Call Waiting ringback. The
call waits in queue until the Transfer Return Interval expires. Calls answered by
using Call Waiting pickup cannot be transferred.
