Feature Reference
The transfer originator does not receive an error tone to indicate that the transfer
was denied. When a call is received on a T1 channel that is programmed to
emulate a loop-start trunk and then is transferred to an outside telephone
number where the caller hangs up before the call is answered, the call is not
disconnected and remains on hold.
Except when One-Touch Hold is used, a transferred call always arrives on an
SA or ICOM button or, when transferred to a QCC operator, on a Call button.
Calls cannot be transferred from an extension programmed for a fax machine,
but inside and outside calls can be transferred to a fax machine. A call
transferred to a fax extension does not return to the originator, but continues to
ring at the fax extension. This eliminates the possibility that a high-pitched fax
tone will be heard by the person who answers the returning 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.
In Release 2.1 and later, a 012 port that is programmed as a generic VMI port
can transfer an outside call to an outside number (trunk-to-trunk transfer).
Release 2.0 and earlier systems can only perform a trunk-to-trunk transfer on
ports programmed as integrated VMI.

Security Alert:
Calling Restrictions (for example, Disallowed Lists, Toll Restriction, Facility
Restriction Levels) should be programmed, as appropriate, to minimize
toll fraud abuse, especially if a single-line telephone is connected to an
integrated VMI port. See "Calling Restrictions" for additional information
on programming calling restrictions.
In Release 4.0 and later releases, whenever a switchhook flash is followed by
onhook status on a single-line telephone, transfer return calls are blocked. This
is done in order to stop unwanted phantom calls from being made to single-line
telephones as a result of telephone handsets bouncing in their cradles. The
handset bouncing in the cradle is interpreted by the MERLIN LEGEND as a
switchhook flash attempt to transfer a call.
Mode Differences
Behind Switch Mode
In Behind Switch mode, the Transfer feature of the host switch is used instead of
the system's Transfer feature when the fixed Transfer button is pressed.
However, to activate Transfer, the fixed Transfer button on an MLX or analog
multiline telephone must be programmed through system programming to send
