Integration
description
The following illustration shows a full-featured UNIVERGE UM8500 installation
integrating with the Sphere system network.
How the integration works
NEC Sphere integration uses a network connection to connect the messaging
system server with the phone system. Voice messaging ports emulate standard IP
trunk connections. The communication between the parties is facilitated by a
series of Voice over IP (VOIP) protocols, such as SIP, RTP, and RTCP, used for call
signaling and voice streaming.
Integration features
The Sphere system integration offers 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
messaging system. The caller then hears the subscriber's personal greeting
and can leave a message.
Caller ID.
The messaging system receives caller ID information from the
Sphere system, if available. This information is displayed in the message
subject line in Microsoft Outlook
®
or other desktop messaging applications.
Easy message access.
A subscriber can retrieve messages without entering
an ID. The messaging system identifies a subscriber based on the extension
from which the call originated. A password might be required.
Identified subscriber messaging.
The messaging system 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, the messaging system notifies the phone system to activate the
message waiting indicator on the subscriber's extension.
Notification to phone and pager devices.
When a subscriber has phone
or pager notification devices enabled, the messaging system calls the device
to deliver the voicemail, fax, or e-mail notification. When the call is received
