3.1.1 Unified Messaging System Overview
Description
The Control Box has a built-in messaging system that provides voice mail services to its subscribers.
Users
The user owns his/her own mailbox.
The following types of users exist in the Unified Messaging system:
•
Subscriber (maximum 1999)
A subscriber is an extension user who has a mailbox assigned to his extension. When subscribers log in
to their mailbox, they can listen to and respond to messages left by other subscribers.
•
System Manager (maximum 1)
The system manager can send broadcast messages.
UM Ports and the UM Group
A port acts as a pathway into the Unified Messaging system, so when a call is directed to the Unified
Messaging system, it requires one available UM port. The total number of available ports is 128.
The UM ports belong to the Control Box's UM group. This group has a floating extension number, which can
be the destination for incoming calls, redirected calls, transferred calls, etc. When incoming calls are
received at the floating extension number of the UM group, calls will hunt starting at the lowest UM port
number.

Conditions
•
As the Unified Messaging system is part of the same system as the Control Box, the Unified Messaging
system's data coordinates with the Control Box settings.
•
Each port is assigned an extension number.

Extension Number
•
When hunting for an available UM port, the Control Box ignores any FWD or DND settings (→ 2.3 Call
Forwarding (FWD)/Do Not Disturb (DND) Features) applied to the ports.
It is possible to call a port in a UM group directly. If a call is routed directly to a port in the group, it is
possible to apply certain features (e.g., FWD) to that port.
•
DSP Resource Usage
Connecting to the Unified Messaging system requires a certain number of DSP resources. If all DSP
resources are in use, this operation cannot be performed. (→ 4.4.2 DSP Resource Usage)
