Telephone Features: Transferring Calls
9.27.6 Centrex Transfer
Centrex Transfer is a feature provided by some line providers on external analog lines. It allows the recipient of a calls on
such a line to transferred that call to another external number. The transfer is then performed by the line provider and
the line is freed. Without Centrex Transfer, transferring an external call to another external number would occupy both a
incoming and outgoing line for the duration of the call.
The following are the supported controls and usages for Centrex Transfer:
· Centrex Transfer Button Operation
The action Flash Hook (Advanced | Miscellaneous | Flash Hook) can be assigned to programmable buttons on DS
and IP phones. This button can be configured with or without a telephone number for an automatic or manual transfer
respectively.
· Manual Transfer
If the programmable button is setup as a Flash Hook button without a target telephone number, pressing the button
returns dial tone to the user. They can then dial the required transfer number and when they hear ringing or an
answer, hang up to complete the Centrex Transfer.
· Automatic Transfer
If the programmable button is setup as a Flash Hook button with a target telephone number, pressing the button
performs the Centrex Transfer to the numbers as a single action.
· Centrex Transfer Short Code Operation
The short code feature Flash Hook can be used with system short codes. It can be setup with or without a telephone
number in the same way as a Flash Hook programmable button detailed above. The line group must be the group of
analog lines from the Centrex service line provider.
· Centrex Transfer Operation for Analog Extensions
Most analog phones have a button that performs the action of sending a hook flash signal. The marking of the
button will vary and for example may be any of R, H, Recall or Hold. For system analog extensions, pressing this
button sends a hook flash to the system to hold any current call and return dial tone.
· To perform a Centrex Transfer, pressing the analog extension's hook flash button should be followed by the
dialing of a Flash Hook short code.
· For analog extension users with Call Waiting enabled, pressing the hook flash button during a call will hold the
current call and connect any call waiting. Therefore it is recommend that analog extension users wanting to use
Centrex Transfer should not also have Call Waiting enabled.
· Transfer from Voicemail/Auto-Attendant
This operation is only supported through Standalone Voice Mail using an Assisted Transfer action with the destination
set to a Flash Hook short code.
Additional Notes
· Addition Prefix Dialing
In some cases the Centrex service provider may require a prefix for the transfer number. If that is the case, that prefix
must be inserted in the button programming or the short code used for the Centrex Transfer.
· Conference Calls
Centrex Transfer is not supported with conference calls.
