Note: Only local subscribers, that is subscribers within a voice mail
domain, can use local mailbox numbers for addressing.
Numeric Address
A Numeric Address, also known as a variable length address, enables
subscribers to address messages to any local or remote recipient in an
organization.
For Modular Messaging—Microsoft Exchange and Modular
Messaging—IBM Lotus Domino, the recipient can be anyone in the
global directory with a Numeric Address. For Modular Messaging—
MSS, the recipient can be any local or remote subscriber in the directory.
Remote subscribers that do not have an administered Numeric Address,
are assigned Numeric Addresses equal to their network addresses. For
details, see Network address
on page 6-7.
Every Avaya Modular Messaging subscriber must be assigned a Numeric
Address. The Numeric Address allows a subscriber to send a message to
any recipient from the TUI without having to know the geographic
location of the recipient. The directory makes all Numeric Addresses
available to all locations within the organization.
US Organizations might choose to use 10-digit telephone numbers (with
the area code) for Numeric Addresses. Other possible schemes include:
! A geographic location code associated with a local mailbox
number
! Mailbox numbers
! Employee numbers
! Short Numeric Addresses, for example “55” for a Help Desk, or
“1” for the office of the CEO
A Numeric Address can have a variable length of between one and 32
digits.
In Modular Messaging—MSS and Modular Messaging—Microsoft
Exchange
1
systems (other than Microsoft Exchange 5.5
2
), Numeric
Addresses can be the same length as mailbox numbers.
With Modular Messaging—IBM Lotus Domino, a Numeric Address
cannot be the same length as the mailbox number.
1. Modular Messaging—Exchange 2000 and Exchange 2003 systems support same length Numeric
Address and mailbox numbers, as of Modular Messaging Release 1.1, Service Pack 3.
2. New installations of Modular Messaging do not support Microsoft Exchange 5.5 server.
