Uniform Dial Plan Features
5. The call is put through speedily. It may go through more than one system
before it is completed. For example, if a user on System A calls Extension
4551, the non-local dial plan may send the call to System B. If 4551 is not
in System B's local dial plan, it may be directed to a non-local dial plan
extension—in System C, for example.
6. At the non-local dial plan extension, the call rings as an outside call. If the
user at the remote networked system has an MLX or ETR display
telephone and the call arrives on a PRI tandem trunk, the display can
provide caller information even for 5-digit extension numbers, such as
MILLS Ext49312. An MLS telephone shows OUTSIDE.The system
manager programs display preferences to supply the extension number,
programmed name label, or both.
NOTES:
Transfers with consultation can be made across the network, but they cannot be
voice-announced. These transfers must be made using telephones; they cannot
be made by CTI-linked PassageWay Telephony services clients. Transfers
between extensions on different networked systems are actually trunk-to-trunk
transfers. Although transfers to non-local dial plan extensions can be made
regardless of trunk-to-trunk transfer prohibitions, such transfers made over
tandem tie trunks behave like trunk-to-trunk transfers, providing no transfer
returns. If the transfer is made over tandem PRI facilities and the non-local
extension is unavailable, the call returns to the transfer originator if the intended
destination is busy, invalid, or has Do Not Disturb active with no coverage.
UDP routing distributes intersystem calls among networked system users, as well
as DID and PRI dial-plan routed calls that arrive from the public switched
telephone network and are routed across the network. It allows the system
manager to prioritize routes used for calls and to set up special routes—for
example, distributing 2B data calls to remote videoconferencing systems. This
routing is distinct from the ARS and Remote Access features used when
extensions on one networked system make outside calls by using lines/trunks
connected to another system in the same private network. For detailed
information on setting up network tandem trunks, refer to the Network Reference .
Users at MLX, ETR, or MLS display telephones can receive incoming
call information for calls from non-local dial plan extensions, but only if
the calls arrive on PRI tandem trunks. A display preference feature
enables the display of extension number information, extension label
(name) information, or both, at display telephones. For more
information, see ''Display'' on page
Non-local dial plan programming can be used to route an extension's
calls to an outside number. This may be convenient when, for example,
an extension user is working at home and wants to receive calls at a
home telephone number.
