Benefits of Avaya Modular Messaging
Avaya Modular Messaging is compatible with several industry 
telecommunications systems, offering service from 4 to 690 ports
1
 and up 
to 100,000
 subscribers. Modular Messaging provides multilingual 
capabilities, thus supporting international operations of customers.
Scalability 
Depending on the product version, Modular Messaging supports from 4 
to 690 ports within a single voice mail domain. For more information on a 
voice mail domain, see 
 on page 4-33.
Modular Messaging—MSS supports a maximum of 144 ports per voice 
mail domain. 
Modular Messaging—Microsoft Exchange and Modular Messaging—
IBM Lotus Domino support a maximum of 690 ports per voice mail 
domain.
For more information on the number of subscribers Modular Messaging 
supports, see 
A voice mail domain can serve a network of switches, provided the 
administrator ensures that the network uses a single switch as a gateway 
to the voice mail domain.
Mobility
With Avaya Modular Messaging, subscribers can send and retrieve 
messages even when they are away from the office. 
Modular Messaging provides subscribers mobile access to their messages 
from any touch-tone telephone, using the Modular Messaging telephone 
user interfaces (TUIs). With the Microsoft Exchange or IBM Lotus 
Domino versions, the TUI provides access to voicemail and corporate 
e-mail messages. With the MSS version, the TUIs provide access only to 
voice, fax, and text messages stored on the Avaya message store server 
(MSS), and not to corporate e-mail messages stored on the corporate 
e-mail store. However, MSS subscribers that desire mobile access to 
corporate e-mail messages can use the Unified Communication Center 
(UCC) Speech Access client or Modular Messaging Web Client. UCC 
Speech Access provides speech access and voice control of corporate 
e-mail and voicemail messages, regardless of whether they are stored in 
1.
The Modular Messaging version determines the number of ports and subscriber mailboxes the 
system supports. For more information, see
