Voice mail domain
A voice mail domain is a group of messaging application server (MAS)
units with a common set of properties, that use one or more message
stores. One can think of a voice mail domain as being a single complete
voice messaging system.
The MAS units in a voice mail domain can be seen as a single "virtual"
server for that domain. This allows the system to be highly scalable, in
that multiple servers can be configured as part of the voice mail domain to
address large capacity requirements. Modular Messaging—MSS supports
a maximum of five MAS units in a voice mail domain, while Modular
Messaging with Microsoft Exchange or IBM Lotus Domino supports a
maximum of ten MAS units in a voice mail domain.
An incoming call can land on any port on any card on any messaging
application server to have access to Call Answering, greetings,
messaging, fax receipt, auto attendant, caller applications, and the full
directory.
Likewise, outbound services such as fax (MSS only), Call Me, and
Message Waiting Indication can also share the communication facilities
across all the servers. This virtual server allows any Avaya Modular
Messaging subscriber in the domain to use the telephone user interface
(TUI) to call in, access their mailboxes, and retrieve their messages. Also,
the virtual server can call the telephone of any subscriber who runs PC
client applications to play back voice messages.
Any changes made to the properties of a voice mail domain are
automatically updated and replicated to all MAS units in the domain.
Voice mail domains provide the ability to store and retrieve properties that
belong to a set of MAS units working together to provide integrated Call
Answering.
An organization can create multiple voice mail domains, for example, one
in each major geographical site.
It is important that all users within the voice mail domain share a common
dialing plan. For additional information on designing voice mail domains
see General rules for voice mail domains
on page 10-2.
Note: An Avaya Message Storage Server (MSS) can be a host to
only one voice mail domain.
