Transfer
Considerations and Constraints
Calls transferred to outside numbers may vary in transmission quality.
The ability to transfer inside calls to outside numbers cannot be specifically
blocked for an individual extension. However, calling restrictions or Disallowed
Lists can be assigned to individual extensions to prevent outward or toll calls.
When an outside call is transferred to an outside number (trunk-to-trunk transfer),
two outside lines are used for as long as the call is in progress.
When a call is transferred to an outside number, the system does not recognize
the transfer until a dialing time-out occurs. Avoid a delay by dialing
the telephone number.
When you try to complete a transfer to an outside number under the following
conditions, the call to the outside destination is disconnected:
The outside line that the incoming call is using is a loop-start line
programmed for unreliable disconnect.
Another inside user has joined the call and the call is now a conference
call, which cannot be transferred.
The transfer originator does not receive an error tone to indicate that the transfer
has been denied. When a call is received on a T1 channel that is programmed to
emulate a loop-start line 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 of a high-pitched fax tone being 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 systems, 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 perform a trunk-to-trunk transfer only on
ports programmed as integrated VMI.
