Integration
description
The UNIVERGE UM8500 unified messaging solution can use the Open
Application Interface (OAI) to integrate with NEC phone systems including
UNIVERGE SV8300. The OAI integration is established over a TCP/IP link between
the messaging system server and the NEC phone system.
How the integration works
There are two basic types of OAI integrations:
●
OAI pure integration .
This type of integration uses only the TCP/IP link to
connect to the phone system. It has an OAI monitoring slot opened with the
phone system and dispatches calls to the enabled voice messaging systems.
This type of OAI Integration provides the most efficient load balancing
capability by dispatching new incoming calls from a monitored number, the
voice mail pilot, to free voice mail ports.
●
OAI UCD - Serial MCI integration .
The OAI Integration Server uses
complementary Message Center Interface (MCI) integration capabilities
through the serial interface. The complementary MCI integration feature of
the OAI Integration Server is not a genuine OAI integration. The integration
does work in Common Channel Interoffice Signaling (CCIS) networked
environments between multiple NEC phone systems when the remote phone
systems do not have OAI or their software revision does not feature call-
forwarding information in the OAI layer. The MCI link is used as
complementary integration support for situations where the OAI layer does
not provide full integration, such as in older, legacy phone system
environments.
Integration features
The SV8300 OAI integration with UNIVERGE UM8500 provides the following
features:
●
Call forward to personal greeting.
When an incoming call is routed to an
unanswered or busy extension, the call is forwarded to the subscriber’s voice
mail. The caller then hears the subscriber’s personal greeting and can leave a
message.
●
Caller ID.
UM8500 receives caller ID information from the phone system, if
available. This information is displayed in the message’s subject line in
Microsoft Office Outlook
®
or other desktop messaging application.
●
Easy message access.
A subscriber can retrieve messages without entering
an ID. UM8500 identifies a subscriber based on the extension from which the
call originated. A password might be required.
●
Identified subscriber messaging.
UM8500 automatically identifies a
subscriber who leaves a message during a forwarded internal call based on
the extension from which the call originated.
●
Message waiting indication (MWI).
When a message is waiting for a
subscriber, UM8500 notifies the phone system to activate the message
waiting indicator on the subscriber’s extension, if it is equipped with one, or
to activate a stutter dial tone.
●
Live Record.
A subscriber can record a phone conversation by pressing the
Live Record button on the Dterm phone. The recording can be saved in the
subscriber’s mailbox for later reference, or forwarded to another subscriber or
group of subscribers.
