UDP Features
A transferred call that returns to the principal extension does not ring on
any corresponding Shared SA buttons. If a transfer originator has an SSA
button for the person receiving the transfer, the LED next to the SSA
button flashes to indicate a ringing call. However, the call is disconnected
if the transfer originator answers.
In Release 6.0 and later systems (Hybrid/PBX mode only), transfers of
outside or non-local dial plan calls to non-local dial plan extensions are
actually trunk-to-trunk transfers. Most extensions, including those
equipped with single-line telephones, can make these calls, regardless of
system programming for trunk-to-trunk transfer. The incoming call must
be on a trunk with reliable disconnect. If a private network trunk is not
available to carry the transferring call, the consultation call can be
callback-queued on the first route, but the transfer must still be in
progress.
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 PSTN.
However, despite prohibitions, the following types of calls are allowed:
A call on a private network trunk transferred to a non-local dial plan
extension
A call on an outside central office line/trunk (except on a loop-start
line without reliable disconnect) transferred to a non-local dial plan
extension
A call on a private network trunk transferred to an outside central
office line/trunk
A call transferred over a tandem PRI trunk 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. However,
most transfer functions operate normally between local and non-local dial
plan extensions, except when transfers are sent by or received by
PassageWay Telephony Services clients with a CTI link. Users at these
extensions must make manual transfers by using the telephones at their
extensions.
Transfers across networked systems over tandem tie trunks do not return
to the transferring extension. If such a call is transferred to a busy or
invalid non-local dial plan extension or one with Do Not Disturb turned on,
the transferred party hears busy or fast busy tone and must hang up and
call back in order to speak with someone. If a transfer is made across a
network over tandem PRI trunks only, it returns to the transfer originator in
the event that the intended destination is busy, invalid, or has turned on
Do Not Disturb.
