Feature Reference
All users except Queued Call Console (QCC) operators can use Forward or
Follow Me to forward calls to another extension. Calls cannot be forwarded to a
calling group.
The factory setting for Remote Call Forward is that users are not allowed to
forward calls to outside numbers. Through system programming, use of the
feature can be allowed for individual extensions.
Forward, Remote Call Forward, and Follow Me send the following types of calls:
Ringing inside calls
Transferred inside or outside calls
Outside calls directed to the extension and received on a tie trunk
Outside calls received on a Direct Inward Dial (DID) trunk
An available calling group member is automatically logged out when the
member forwards his or her calls. If a calling group member logs in while calls
are being forwarded, Forward or Remote Call Forward is automatically
canceled.
Forward, Remote Call Forward, and Follow Me do not send the following types
of calls:
Voice-announced inside calls
Calls received on a Cover button
Returning parked or transferred calls
Callback calls from the system
Calls received on a Shared SA button
Calls received on a Call button on a QCC
Calls transferred from a calling group for a voice messaging system
(VMS) connected to a jack programmed as generic VMI.
Calls forwarded from other extensions
Calls received on a personal line (an outside line assigned to a button on the
telephone) are forwarded to outside numbers using Remote Call Forward only
under the following circumstances:
The extension must be assigned as the principal user of the personal line
through system programming. Only one extension can be the principal
user for a given trunk.
