VMSC - Voice Mail Domain (VMD) Configuration
Understanding Offline Access
Note: For more information about Offline Access, see the Avaya Modular
Messaging Concept and Planning Guide.
You can configure Offline Access to call-answered messages at voice main domain
level, via the Messaging dialog box, Offline Access tab. See Messaging - Offline
Access Tab on page 3-127.
With Offline Access, subscribers can use the Telephone User Interface (TUI) to access
recently recorded call-answered messages, even when the message store server
(Avaya MSS) is not accessible. Subscribers cannot use the TUI to send or receive
voice mail messages, however.
The Modular Messaging system evaluates whether it needs to use Offline Access on a
call-by-call basis.
Offline Message Storage
If the voice mail domain only contains one Messaging Application Server (MAS), there
is only one local offline message store. If the voice mail domain contains more than
one MAS, offline messages are saved both locally and remotely:
! Local Offline Message Store A folder on each MAS in the voice mail
domain.
! Remote Offline Message Store A folder on the file server. This server is
networked to the voice mail domain but is not a message store server and
not usually an MAS.
Note: You must set each offline message store folder as a shared
folder and configure the permissions. For these procedures,
see Configuring the Offline Message Store Folder on page
3-131
When a call-answered message is recorded, the TUI saves it and sends the message
file to the message store server (Avaya MSS).
If Offline Access is enabled, the message is also delivered to the local offline message
store folder on the MAS and the remote offline message store on the file server. The
remote store holds all recently recorded call-answered messages for the voice mail
domain; the local store only holds those messages received on a particular MAS.
By default, call-answered messages are retained for offline access for 24 hours, then
deleted. This period is configurable for a voice mail domain. If the remote offline
message store disk space is full, no further call-answered messages are taken and a
major alarm is generated, MT PERF 26.
