Avaya Modular Messaging Concepts and
Planning Guide
Calculating the number of desktop users per voice
mail domain
A Modular Messaging—Exchange or Modular Messaging—IBM Lotus
Domino configuration supports up to a maximum of 100,000 local
subscribers in a voice mail domain. The customer implementation of the
e-mail environment determines the number of desktop users.
The Modular Messaging Message Waiting Indicator (MWI) feature is
limited to 7,000 subscribers for Modular Messaging—Exchange and
Modular Messaging—Domino, within a voice mail domain.
Subscribers that are not enabled for MWI alerts can rely on the
notification mechanisms provided by the Graphical User Interface (GUI)
clients for being notified of new voice messages.
Modular Messaging—Message Storage Server (MSS) supports two types
of standards-based e-mail clients:
! E-mail clients based on Internet Message Access Protocol 4
standards (IMAP4 clients).
! E-mail clients based on Post Office Protocol 3 standards (POP3
clients)
The Modular Messaging offers show the number of ports that are required
to provide service to a given number of subscriber mailboxes. The
number of mailboxes is based on port calculations alone. The number of
IMAP4 and POP3 clients that Modular Messaging supports is limited by
factors such as CPU occupancy and the maximum number of IMAP4
sessions supported.
IMAP4 client limits
With a Modular Messaging—MSS system, all active IMAP4 clients
require an IMAP4 session on the Avaya MSS. Currently, Modular
Messaging—MSS supports up to 1,000 simultaneous IMAP4 connections
to an MSS. The Client Add-in for Microsoft Outlook application,
Modular Messaging Web Client, and the Unified Communication Center
(UCC) Speech Access client count towards this limit. Subscribers may
also be using UCC Speech Access and an IMAP4 e-mail client
simultaneously.
Use the following rule for calculating IMAP4 client limits:
(User population x [% given IMAP4 access] x [% logged in at one time])
