Features
Uniform Dial Plan Features
Transfer
continued
Local users can make the types of calls listed below, regardless of system
programming for trunk-to-trunk transfers:
A call on a private network trunk transferred to a non-local dial plan
extension
A call on an outside central office line/trunk transferred to a non-
local dial plan extension
A call on a private network trunk transferred to an outside central
office line/trunk
Other trunk-to-trunk transfers are prohibited. If the system manager has
prohibited an extension from making trunk-to-trunk transfers, it is still
prevented from transferring inside or outside calls to another local system
trunk connected to the public switched telephone network.
Consult the Network Reference for information about restricting calls on
extensions in a network. Note that if an extension receives an outside call
transferred from a non-local extension over a tandem trunk, the user can
then transfer this outside call to an outside PSTN facility, possibly
bypassing intended restrictions.
Most transfer functions operate normally between local and non-local dial
plan extensions, except when transfers are performed by or received by
PassageWay Telephony Services clients with a CTI link. However, a call
transferred to a non-local dial plan extension with an MLX display
telephone does not receive the same call information that an inside
transfer does. Only the extension number and label (if programmed) of
the transferring extension are shown.
Transfers across networked systems only return to the transferring
extension if the transfer is routed over tandem PRI facilities. If a call is
transferred to a busy or invalid non-local dial plan extension over tandem
tie trunks, the transfer originator hears a busy tone and must hang up and
call back in order to speak with someone.
